– Rumbar Pirates find Laboon: Chapter 487, text box indicates it as 50 years ago from 1522

1473

– Linlin is impregnated: Given that Perospero was born on March 14th, Linlin had to be impregnated the previous year

1474

– Perospero is born: SBS Vol 88

– Gekko Moriah is born: SBS Vol 58

– Brook and everyone else dies: Chapter 487, three years after they meet Laboon, Brook's soul returns to his body, in 1475. This is confirmed by the fact that Brook is still surprised to be a skeleton. We know it took a year for the soul to return, so they died the year prior, 1474. His soul takes a whole year to return to his body, as described to the Straw Hats during his introduction

1475

– Trebol is born: SBS Vol 75

– Kuzan is born: Vol 1000

– Compote is born: We know that Perospero is 50 while the triplets are 48. Given that Big Mom gave birth once every year, Compote had to be born between the two, as no one else could've. Flampé also remarked that Katakuri had 38 younger sisters out of 39 Charlotte family daughters, confirming Compote is older than him

– Brook's soul returns to his body: see above in 1474

– Katakuri, Daifuku and Oven are born: SBS Vol 87

1477

– Kuma is born: SBS Vol 58

– Urouge is born: SBS Vol 68

– The Charlotte quintuplets are born. We know that between Katakuri (48) and Cracker (45) there had to be two births (47 and 46 respectively). One of them has to pertain to Opera and his siblings, while the other has to pertain to some daughters. This very likely pertains to Amande, who was shown to have at the very least one twin. While it is possible a 2nd daughter alone might've filled her place, it is unlikely, given how Brûlée, the 8th daughter, was shown to be not much younger than Katakuri. However, we do not know who was born first, Opera or Amande, so the two of them were born in 1477 and 1478 respectively or vice versa

– April, Roger leaves Rouge pregnant with a child: Chapter 550, Sengoku claims Rouge became pregnant 20 months before Ace's birth, which was January 1st 1502

– Roger meets one last time with Whitebeard: We know this has to be August, since Teach joined the Whitebeard pirates at the age of 16. Since his birthday is on August 3rd and Whitebeard mentions him being in his crew in that scene, it had to take place in August, likely just before Roger gave himself I to the marines

– Duval is born: We see him in chapter 0 as a newborn. Theoretically, he would be born after Roger's death in September, as we see his parents claiming the pirate age cursed him, but his birthday contradicts this, being in August. This is technically a mistake, but it could be justified with the fact that we don't see Duval's birth, we simply see him at a very young age, so he could be barely a month old

– Bonney is born: SBS Vol 68. Oda specifically comments on how Bonney's age is only based on her appearance, as she could very well be older or younger thanks to her powers

– Crocodile is defeated by Whitebeard: SVS Vol 78, Oda claims Crocodile was somewhere around the age of 25 when he was defeated by Whitebeard

1504

– Charlotte Mascarpone and Joscarpone are born: okay, so we know that the Charlotte decuplets are 18 years old each of them. This means they are born on 1506. The daughters of the Decuplets are numbers 30 through 34 and with Joscarpone being the 29th daughter, it means she was born before then. However, Mascarpone is the 34th son, while the decuplets are 36-40th. This means someone was born in between, this someone being the 35th son Yuen. This means a year before the decuplets were born Yuen had to be born, since it couldn't have been a female, as there were none between Joscarpone and the female decuplets. That means the year before Mascarpone ad Joscarpone were born, as being both male ad female they are the only possibility for being born. I know this sounds complicated, but it all makes sense once you put it together!

– May 5th: Luffy departs from Foosha Village: Chapter 598, Ace and Luffy vow to leave Dawn Island when they each turn seventeen

– Around Day -4: As suggested by the moon phase. It's an estimation (hence the ~)

– Around Day -2: Chapter 94, The party for Arlong's defeat lasts two nights, the Straw Hats leave the day after

– 4:28-4:30: Chapter 205 and onwards, the times can all be seen on the clock. I haven't bothered to include the specific seconds, since it would be too cluttered

– Day 17: Chapter 213, Luffy has slept for three days

– 12 AM: Chapter 214, Vivi will meet them in 12 hours at 12 PM

– 12 PM: See above

Skypiea:

– Day 18: There is no indication of anything big happening between Alabasta and Jaya, it's implied it all takes place in the same day, take this with a grain of salt

– 10 AM: Chapter 235, it's mentioned the Knock Up stream takes place at 10 AM, making it the morning after the night

– Day 20: We see the Straw Hats sleeping, a day passes

– ~June: Around 30 days have passed. While not precise when, around a month has passed

– A few days pass: Chapter 301, the celebration lasts a few days, it's also mentioned that Nola danced for a few days. The Straw Hats don't change clothing nor bandages, so it couldn't have been that long, likely just a couple days

CP9 Saga:

– Day 1: The Straw Hats leave Skypiea with the gold. They fall to the Blue Sea quickly due to a leak in the same day and after getting into trouble with sea monkeys they discuss about the money and are attacked by the same sea monkeys right after. They find Long Ring Long Land immediately after the attack from the sea monkeys

– Day 4: Chapter 322, the Straw Hats stayed at Long Ring Long Land to rest for four more days. They depart and after three days the events of day 8 happen

– Day 15: Sunny has been completed in three days since the party

Thriller Bark:

– Some days pass: There is no specific time frame between Water 7 and Thriller Bark, but some time has passed. Despite that, it hasn't been much, as many of the Straw Hats still comment about the new functions of the Sunny, so again, a couple days at most

– Day 1: The events on Thriller Bark

– 12 AM: Chapter 449, Clock is seen several times

– Day 2: We see the Dawn rise after the day on Thriller Bark

– Day 3: Chapter 486, a day has passed

– Day 5: Chapter 489, two days have passed

Paramount War:

– Some days pass: Chapter 490, "several days later". The Straw Hats have a few adventures, but Sabaody isn't that far away from Water 7 as described in several occasions

– Strong World: the events take place after Thriller Bark since Brook has joined, but before Sabaody since the Straw Hats are together. The movie isn't considered canon by Oda as he considered unfair for manga only readers, but it's considered semi-canon to an extent, as it could've perfectly happened within the storyline

– ~July: Taking into account the several days that have passed, about another month has passed. Again, we don't know how much, but about 30 days have passed (20 known ones, plus three "some days" instances)

– Day 1: Events at Sabaody

– 04:00 PM: Chapter 501, Duval mentions the auction opened at four and half and an hour has already passed

– Day 2: Chapter 514, We see the sun fall and rise over some panels, so a night passes

– Day 3: Chapter 521, Gloriosa mentions Luffy punched Charloss just two days ago. A day has passed since Luffy landed, since he slept "for a long time" in his cell according to the Kuja

– Day 4: Hancock mentioned departing in the morning

– Day 8: Chapter 521, Gloriosa mentions it takes a marine ship four days to reach Impel Down. She also mentions Ace's execution is in five days from then (Luffy departs the morning after she says six days) and it fits quite well, since Luffy arrives at Impel Down the day before the execution

– 06:00 AM: Chapter 525, 33 hours till execution. Chapter 533, Momonga mentions the execution will be at 3 PM

– 10:00 AM: Chapter 533, text box

– 01:00 PM: Chapter 536, text box

– 11:00 PM Chapter 537, Inazuma mentions Bentham has been sleeping for ten hours

– Day 9: Midnight has passed

– 00:05 AM: Chapter 538, Clock

– 03:05 AM: Chapter 538, Clock

– 07:10 AM: Chapter 538, Clock

– 08:08 AM: Chapter 538, Clock, 8 hours have passed as well as mentioned by the text box

– 08:40 AM: Chapter 539, Luffy has been eating for half an hour

– 09:00 AM: Chapter 539, Domino mentions Ace will be handed over at 9 AM, no delays accepted

– 09:45 AM: Chapter 541, Clock

– 12:00 PM: Chapter 549, it's mentioned it's three hours till the execution schedule

– 01:30 PM: Around an hour and a half passed since the beginning of the war (Sengoku's speech, right before Whitebeard enters, is at 12 PM)

– ~Day 24: Chapter 582, around two weeks have passed

– ~August: Chapter 596, it's brought up that Franky disappeared just under a month ago, which is when the Straw Hats prepare for the timeskip. So after that, August already begins

Timeskip:

I'm only going to bother to give a source for the events that happened at a specific point, since all the others are just "this happened in the timeskip/this happened over the past two years"

1523

– Bege plans to assassinate Big Mom: Chapter 869, Bege mentions his plan took over a year to prepare. This means it had to be prepared sometime in 1523

– Bartolomeo becomes a supernova: Chapter 704, Dagama mentions Bartolomeo became a supernova one year ago

– Drake joins as a headliner: Chapter 912, mentioned by Hitetsu to be one year ago

1524

– Just further confirmation that this IS 1524: Chapter 801, Doflamingo mentions Roger arrived at Raftel 25 years ago. We know he arrived in 1499 thanks to Chapter 0, so it all lines up. Judge also mentions Sanji left the Baratie a little over two years ago (which would be around a year and three/four months ago), Chapter 839

– O-Tama eats rice for New Year's: Chapter 911, Hitetsu says O-Tama can only eat rice on new year's and her birthday

– Totto Land's bi-yearly soul gathering takes place: We see it happen when the Straw Hats arrive there, so six months before another had to take place

– Around February, Rayleigh returns to Sabaody: Chapter 598, Luffy mentions Rayleigh left six months ago

– Stelly assassinates the king and prince: Chapter 905, said to happen a few months before the Reverie

– Urouge infiltrates Big Mom's territory: We know this happened more recently than the others, since Urouge was still recovering from his wounds at the Balloon terminal

– Capone Pez is born: He's still a newborn and Bege makes mentions of him just recently coming to light, so his birth had to be recent. He's the youngest named character in the series!

– Day -4: Chapter 807, Wanda mentions Jack arrived 17 days ago

– 6 PM: Chapter 809, on the clock and text box. This obviously goes on for the following days, but I spared you the continuous hours

– Around August: The two years actually started from when Luffy sent out the message, not from when they separated at Sabaody, as Brook mentions in chapter 598 that it's his two-year anniversary since he started performing. Luffy also mentions that Rayleigh trained him for "a year and a half and then six months passed", implying his training lasted around 24 months exactly

Punk Hazard:

– Day 1: It's unknown how long the trip from Sabaody to Fishman Island took given the darkness of the depths, nor how long they spent on Fishman Island partying till they left. However, the text box in chapter 654 implies their journey leaving Fishman Island happens right after they leave and we see them go all the way to the surface where they emerge in the waters of Punk Hazard (the sea is visibly and mentioned on fire). All the events of Punk Hazard take place

– Jack wipes out the Minks on Zou: Chapter 810, the gas was released on the fifth day of the battle. Also confirmed later in Chapter 811

Dressrosa:

– Day 2: Chapter 699, a single night passes. All of Dressrosa takes place over one goddamn long afternoon

– 3 PM: The time of the exchange, mentioned several times, such as in chapter 711

– Day 3: Chapter 795, text box mentions it being the following day. Also referenced later in chapter 807. It's also mentioned in Chapter 811 that it's almost been 48 hours since the gas was released

– Day 5: Chapter 796, text box mentions it's been three days after the battle against Doflamingo

Zou:

– Day 6: In Chapter 807 Robin mentions the day at Dressrosa was eleven days ago. Since this takes place a week before the Straw Hats land on Zou, it means a day has passed since the fleet was formed

– Day 11: Sanji is abducted: Chapter 811, Brook mentions it happened just two days ago (from Day 13)

– Day 13: Chapter 802, a week has passed. Also see above, eleven days since the battle of Dressrosa

– 06:00 PM: Chapter 809, Inuarashi falls asleep and Wanda explains

– Day 14: The night passes throughout the arc. In Chapter 824 it's mentioned this is the very same day they leave Zou and Luffy and the group are starving after making a culinary mess

– Some days pass: Chapter 824, Nami mentions Luffy wasted a week's worth of supplies. So they couldn't have starved for that long, given that their journey to Totto Land was intended to be under a week. The same chapter mentions "a few days later", while the following says "a few more days later", that's when they meet the Vinsmokes

Whole Cake Island:

– Day One: Meeting Reiju, arrival at Cacao Island

– Day Two: Chapter 830, the night passes

– Day Three: Another night passes

– 02:00 PM: Chapter 845, Clock. It was day right before the storm hit, so this is PM, not AM

– Day Four: Yet another night passes. In the morning Luffy and Sanji make up

– 05:00 AM: Chapter 857, Jinbe mentions the tea party being at ten in the morning, five hours from then

– 05:45 AM: Chapter 858, text box

– 06:30 AM: Chapter 858, text box and clock

– 06:40 AM: Chapter 858, text box

– 07:30 AM: Chapter 859, Sanji states it plus clock

– 09:00 AM: Chapter 859, it's mentioned the tea party starts in an hour

– 09:41 AM: Chapter 860, clock

– 10:00 PM: Chapter 857, mentioned several times, such as in Chapter 857

– 12:00 PM: The clock on Streusen mentions this time, but it's been pointed out that it does so too on the day before, meaning it might be broken. The anime also uses this time, so it's a bit hard to call it official, but it does line up perfectly with the rest of the information, so I left it there mostly for clarity

– Around 2 PM: Chapter 880, it's mentioned that Pudding requested preparations for the cake at Cacao Island and that those preparations were taken around an hour ago from 3 PM. It isn't exactly specified if she contacted them an hour ago or it was an hour ago they got the things done on Cacao, but give or take around that time

– 3 PM: Chapter 880, Clock

– 3:40 PM: Katakuri mentions the merienda is 40 minutes late, while the chefs mention it was intended at 3 PM

– 4 PM: Chapter 884, text box and clock

– 5:40 PM: Chapter 885, Clock. It's slightly bent, but it does indicate 5:40

– 5:55 PM: Chapter 885, Sanji mentions 6 PM is in five minutes

– Around 6 PM: The cake leaves the factory right after

– 9 PM: Chapter 889, text box and clock

– 9:30 PM: Chapter 891, text box and clock

– Slightly before 10 PM: Chapter 892, Nami mentions 1 AM is a little over three hours away

– 9:50 PM: Chapter 892, Clock

– 10:10 PM: Chapter 894, text box and clock

– 10:50 PM: Chapter 894, text box and clock

– 11:08 PM: Chapter 894, text box and clock

– 11:36 PM: Chapter 894, text box and clock

– 12:05 AM: Chapter 894, text box and clock

– 12:28 AM: Chapter 896, text box and clock

– 12:29 AM: Chapter 896, Clock, a minute has passed

– 12:37 AM: Chapter 896, text box and clock

– 12:39 AM: Chapter 896, Clock

– 12:40 AM: Chapter 896, text box and clock

– 12:43 AM: Chapter 896, text box and clock

– 12:45 AM: Chapter 896, text box and clock

– 12:47 AM: Chapter 896, text box and clock

– 12:50 AM: Chapter 896, text box

– 12:55 AM: Chapter 86, text box and clock, plus mention by Oven

– 12:56 AM: Chapter 897, text box and clock

– 12:59 AM: Chapter 897, Clock

– 05:20 AM: Chapter 902, Clock

– Day five: We see Midnight pass at the mentions of 12:05 AM and in this early morning the Straw Hats escape Totto Land, leaving for good at around five in the morning. In chapter 903 we see that Chopper hasn't stopped tending to Luffy's wounds as he's the only one not to have changed clothing and Luffy is still in his bandages and his bed without having moved an inch, so it's supposedly later in the same day. It's also Nami's first mention of Zeus, so she would've likely mentioned it before had more than a day passed. News are often produced at incredible speeds, so it's not absurd that Morgans delivered the news by the following day in a special issue

– Reverie in two days: Chapter 902, given Ivankov and Sabo just seeing the newspaper, this is the same day. Reverie to take place in two days according to text box

– Day Six: Chapter 906, it is mentioned the Reverie begins the day after, meaning a day has passed from the previous chapter

– Day Seven: Chapter 908: A day has passed according to text box, the Reverie begins

– Straw Hats land at Wano: Chapter 910, the Straw Hats receive the newspaper detailing the events of the previous day, meaning it's still all in the same day the Reverie began

To be continued....
