With his final words, he encourages people to go search for the One Piece treasure, leading to a boom in piracy that marks this moment as the end of Roger’s Era and the beginning of the Great Pirate Era. This Era would also come to be known by some as Whitebeard’s Era. Several figures that would leave their mark in the future attend Roger’s execution, including the likes of Crocodile, Doflamingo, Moria, Mihawk, Dragon, Shanks, and Buggy (Chapter 1: The series begins. It’s worth noting that Sengoku commented Ace was born 15 months after Roger’s execution, which would mean Roger was executed around September 1500 if we rely on Ace’s birthday)
Roger leaves Portagas D Rouge 1500 (24 years ago) April – Roger leaves his lover Portgas D. Rouge pregnant with a child (Chapter 550: Sengoku claims Rouge became pregnant 20 months before Ace’s birth in 1502. If taking Ace’s birthday into account, this would set it at around April 1500)
It was said that Gol D. Roger was acting less like a pirate and more like a man in love while on the island and the World Government searched the island for any signs of his child. Portgas D. Rouge lived here and gave birth to the infant that she would name "Gol D. Ace" after sustaining him in her womb for twenty months to protect the child from the Marines and government officials. After giving birth to Ace, she died from the extended pregnancy.[1]

His mother, who kept Ace in her womb for 20 months to avoid detection by the Marines, dies shortly after delivery, and thus Ace is taken in by Monkey D. Garp as requested to him by Roger. Busy with his duties though, Garp leaves Ace in the care of his mountain bandit friend Dadan at Dawn Island and Ace takes the family name “Portgas” to hide his heritage (Chapter 159: Luffy says that Ace is three years older than him)
1507 (17 years ago) – Donquixote Rosinante, now a Marine, infiltrates his brother’s crew, the Donquixote Family, to spy on them as an undercover Marine. Doflamingo passes the seat and name “Corazón” from Vergo to his brother Rosinante (Chapter 766: Vergo claims Rosinante infiltrated 14 years after his disappearance when he was 8; Vivre Cards: Rosinante became Corazón 17 years ago)

1511 (13 years ago) – The Marines agree to buy the Ope Ope no Mi from the Barrels Pirates on Rubeck Island, but Rosinante steals the fruit from their base on Minion Island and feeds it to Law, saving his life from the Amber Lead Disease. Doflamingo entraps the Barrels Pirates in his birdcage and kills both captain Diez Barrels and his own brother Rosinante, though Law manages to survive and escape. Meanwhile, Barrels’s son, Diez Drake, manages to escape the island and his abusive father in the chaos of the birdcage and is saved by the Marines. Sengoku takes him in and raises him to become a Marine (SBS Vol. 84: Oda says Law is 13 years old when Rosinante dies and when he meets Bepo)
1512 (12 years ago) – During the burning of the Grey Terminal Incident, the Revolutionaries are contacted about the struggling rebellion in Toumi in the South Blue. Kuma heads there with his powers to aid the rebels, finally ending the civil war and liberating the country (Chapter 1098: two years have passed since 14 years ago. We see Ivankov mentioning the Grey Terminal Incident that just took place as Kuma heads out)
1512 (12 years ago) – As an enslaved wife of a Celestial Dragon, Ginny is forced to bear a child. During this time, Elder Planet St. Saturn conducts drug experiments on Ginny, causing her to develop Sapphire Scales. On September 1st, Ginny’s child Bonney is born, carrying the same disease, though it wouldn’t visibly manifest until several years later. Saturn experiments on the baby Bonney by trying to feed her the Toshi Toshi no Mi fruit as an extract, which proves a success. However, disgusted by her disease, Ginny’s Celestial Dragon owner releases her, so Ginny attempts to return to the Sorbet Kingdom. Though sunlight worsens her condition, she forces herself to make the trip back to the Sorbet Kingdom so that her child can survive safely, and ultimately succumbs to her disease. Kuma promises to raise Bonney in her place (Chapter 1098: Ginney died two years after 14 years ago, and after the Grey Terminal Burning; Chapter 1098: Bonney is 5 as of 7 years ago. Ginny also died 12 years ago, so it lines up)
1518 (6 years ago) – The One-Man Revolution: King Bekori returns to the Sorbet Kingdom and attempts once more to divide the country in half, setting up a great burning to the island’s southern side. Kuma defeats and later kills Bekori to free the country, becoming the country’s king, though he cedes power to King Bulldog. However, the newspapers frame Kuma as a despot who took over the throne by force, nicknaming him the “tyrant” and forcing him to escape to sea to become a pirate. Kuma sails the seas for the next two years looking for a cure for Bonney (Chapter 1098: one year has passed from 7 years ago, it’s also been 16 years since the previous incident)
Eustass “Captain” Kid unites the four gangs of his home kingdom in South Blue after the royalist gang ruling over the country kills his friend Victoria, deposing them from their rule. Alongside the other gang leaders, Killer, Heat, and Wire, Kid forms the Kid Pirates and sets out to sea, earning notoriety in the South (Chapter 999: Ace mentions Kid is starting to get notorious in the South Blue 4 years ago; SBS Vol. 104 details Kid’s backstory)

April Summit War Day 1 – The Celestial Dragon Incident: The Straw Hats reach the Red Line and meet the mermaid Camie. They help her rescue Hatchan from the Flying Fish Riders, and are led to the Sabaody Archipelago to meet Silvers Rayleigh, who agrees to coat their ship. However Camie is captured by slave traders, and Luffy ends up punching Celestial Dragon St. Charloss to save her, sparking the start of a big incident. Admiral Kizaru is summoned to the island to take care of the Straw Hats, and overwhelmed by strong enemies, Kuma saves them from the brink of defeat by sending them away to faraway islands (Chapter 490: “a few days later” have passed from Thriller Bark to Sabaody. The amount isn’t specified, however it can’t be that long since not long has passed since Ace’s arrest and his planned execution. In Chapter 522, Gloriosa also mentions that from Amazon Lily to Sabaody it’s slightly over a week, despite Amazon Lily being located further back than Enies Lobby, meaning the journey from Water 7 to Sabaody is just over a week. Still, since we lack specific dates, from here to the rest of the saga, the days will be marked as “Summit War Days” for the purpose of tracking, but they should generally fall within April or May)
April SWDay 10 – The Summit War: the Marines are set to execute Ace at 3PM in Marineford. As they expected, the Whitebeard Pirates and their fleet show up to retake Ace, sparking the Summit War that would unfold over the following day, with the Emperor’s forces clashing with the Marines and the remaining five Warlords. Over a grueling war, Luffy manages to succeed in freeing his brother, but ultimately Portgas D. Ace is killed by Admiral Akainu as he tried to protect his brother. Blackbeard storms Marineford after his raid on Impel Down and kills Whitebeard as well, managing to steal his fruit by becoming the first man to have eaten two devil fruits. The war spirals out of control but it is stopped thanks to the efforts of Koby and Shanks, who arrives on the battlefield to end the war. Luffy manages to escape the battlegrounds thanks to the help of Trafalgar Law (Chapter 538: eight hours have passed since midnight. Ace is set to be executed at 3PM, so the Summit War unfolds over the next day)
1522-1524 (2-0 years ago) – The Kid Pirates get into conflict with the Red-Haired Pirates, where Ben Beckman takes Kid’s arm (Chapter 928: Kid lost his arm to the Red-Haired Pirates prior to entering Big Mom’s territory, which took place closely before Fishman Island)

Later events in Chapter 928 detail his incursion)
Around February 7th – On the news, Donquixote Doflamingo resigns from the Seven Warlords and abdicates to the Throne of Dress Rosa. In reality, Doflamingo used his knowledge of Imu’s existence to blackmail CP0 into delivering a false report, in order to trick Law into a trap. The newspaper also reports Luffy and Law’s alliance, as well as an alliance between Kid, Hawkins, and Apoo, to take down Shanks, though Apoo is secretly working for Kaido (Chapter 699: morning paper)
Around February 6th – Having left Fishman Island, the Straw Hats enter the New World, but are lured to Punk Hazard after receiving a distress call. On the island, Luffy meets Law, who proposes him a plan to take down one of the Four Emperors, Kaido. This involves kidnapping Caesar and destroying the S.A.D. production plant on the island, rescuing the children being experimented on by Caesar in the process. Caesar unleashes his renewed deadly gas Shinokuni on the island, but the Straw Hats, teaming up with Law and Smoker’s G-5 Marines, are able to escape and capture Caesar. Monet and Vergo attempt to stop their efforts for Doflamingo’s sake, but both end up dying during the incident. Proceeding with their plan, Law gives Doflamingo an ultimatum to leave the Seven Warlords in exchange for Caesar’s life. At the same time, the Straw Hats meet Kin’emon and Momonosuke, and let them join them on their journey (Chapter 699: Punk Hazard took place a day before Dress Rosa)
Around February 8th – Kaido jumps off of the sky island Ballon Terminal after feeling depressed that Doflamingo got captured. He once again survives, but he then goes on to fight Kid’s alliance after Apoo backstabbed Kid.

Law’s crew is also jailed in order to lure him out (Chapter 933: in the morning, nine days remain for the raid)
March 9th – News of a wildfire in Kuri go around Wano, as the Beasts Pirates mistakingly attack Ashura Douji’s bandits, as well as the funeral of Komurasaki, and the capture of the Witching Hour Boy, who turns out to be Shimotsuke Yasuie, though he is only pretending to be the noble thief. Yasuie is publicly executed by Orochi, but his sacrifice helps cover up the actions of the allies. Law meanwhile trades himself to be jailed in exchange for his crew to be freed. Big Mom arrives at Udon and regains her memories, but is captured by Queen and taken to Onigashima, where she clashes with Kaido. With them absent, Luffy and his allies take over Udon, but are able to keep it a secret from Kaido’s forces (Chapter 941: morning rises after night fell on the previous chapter)
March 17th – Raid on Onigashima: As Wano celebrates its Fire Festival, the Ninja-Mink-Pirate-Samurai Alliance prepares its attack on Onigashima. Kanjuro reveals himself as the traitor, but his sabotage is foiled when Kin’emon’s mistake allowed the allies to gather and strike back. Rejoined by Jinbe just in time, the Straw Hats and their allies storm Onigashima and begin a long battle against the Beasts Pirates overnight, as Kaido attempts to enact the New Onigashima Plan by moving the entire island on the Flower Capital. On the rooftop, the Supernovas clash against the Emperors, and the Beasts Pirates fall one by one as Sanji destroys his raid suit and Zoro awakens Conqueror’s haki. Law and Kid team up to defeat Big Mom, while Momonosuke is aged by 20 years to prevent Onigashima from falling thanks to Yamato’s help. In his clash against Kaido, Luffy finally awakens his fruit, allowing him to fully transform into the figure of Nika, marking the return of Joyboy’s user upon the world. Luffy defeats Kaido and liberates the Wano Country, and Momonosuke rises up as the new shogun of Wano. Big Mom, Kaido, Orochi, Kanjuro, Hawkins, X Drake, Izo, and Douji all presumably die in the incident (Chapter 955: the day of the raid, two weeks after March 3rd as stated in Chapter 919)
Around March 24th – Luffy and Buggy are promoted as the new Emperors in Kaido and Big Mom’s place, with Luffy lauded for his exploits at Onigashima and Buggy being mistaken as the leader of Cross Guild. The Government attempts to cover up Luffy’s transformation as Nika but Morgans decides to publish it anyway, as Luffy, Kid, and Law all receive a 3,000,000,000 belly bounty. All the other Straw Hats get bounty increases as well (Chapter 1051: seven days have passed since the Raid, though it’s possible the newspaper may have been from slightly earlier as news struggle to reach Wano)
April 7th-11th – The Kid Pirates reach Warland Elbaf, but are completely annihilated by Shanks upon attempting to attack it, eradicating the pirate crew.
