List of Splatfests in Splatoon 2

All the details about Splatfests in Splatoon 2 are listed here.

Splatfests and results
This section lists all Splatoon 2 events and their start times. On each event in the tables, the first choice is always sided by Pearl while the second is sided by Marina.

Starting with With Lemon vs. Without Lemon, the Japanese Splatoon Twitter account started revealing more detailed results for Splatfests in the Japan region, giving percentage results to two decimal places. Starting with Version 3.0.0, instead of the whole numbers used previously, these detailed results were expanded out to all regions as the default method to display results in game, and was retroactively applied to all results displayed in SplatNet 2.

Data
The game only makes results available as percentages. However, the raw data has been obtained from SplatNet 2. After the Action vs. Comedy Splatfest, Nintendo stopped making this data available.

Stages
Unlike in Splatoon, where three stages are played for the entire Splatfest, stages in Splatoon 2 change every two hours with two being any random stage and the third being Shifty Station. Shifty Station's layout changes per Splatfest. The Splatfest World Premiere had only two stages per two hours. Since the World Premiere lasted four hours, only four stages were available.

Errors and Oddities

 * For the Agility vs. Endurance Splatfest in Japan, the Inkling script on the tees (which have always been designed to be familiar enough to users to be read as the team names) were marked with the opposing team's names, with the Agility tees reading "ENDU RANCE", and the Endurance tees reading "INSTANT", meaning "instant power", a more literal translation of the Japanese text for the Agility team.
 * If the Mayo vs. Ketchup Splatfest had combined results instead of segregated, Team Ketchup would have been declared the winner, taking both the Popular Vote (Due to Ketchup's greater popularity in the West) and Team Play (Due to Japan outplaying the other two regions combined in that category by a factor of roughly 8.7 to 1).
 * Popularity: Mayo 679318 - Ketchup 830583
 * Solo Play: Mayo 1529074 - Ketchup 1480605
 * Team Play: Mayo 72695 - Ketchup 75073
 * After the version 4.0.0 changes of score method, players who didn't launch Splatoon 2 after the previous Splatfest got the Splatfest results based on the new score system which were pretty one-sided.

Superlatives

 * For the second Splatoon 2 Splatfest, Mayo vs. Ketchup, the colors white/cream and red were used. This is the first time that these colors have been used internationally in the entire Splatoon series; the Japanese Lemon Tea vs. Milk Tea featured white/tan ink for Milk Tea and the European Barbarian vs. Ninja featured red ink for Barbarian.
 * Team Chicken (Chicken vs. Egg) would later use a solid white ink for the first time in North America and Europe. Japan wouldn't see solid white ink until Team Hello Kitty in the first round of the Sanrio Splatfest Tournament.
 * There have been to date 8 instances where one side swept all three categories. 4 in Pearl's favor (Vampire, Sweater, Gherk-OUT, Salsa), and 4 in Marina's favor (Advanced Technology, Modern, Koshian, Save It.
 * Four of these (Modern, Koshian, Salsa, Save It), were under the new scoring system introduced in Version 4.0.0
 * Only 5 teams (Ice Cream, Ketchup ❌, Fries, Front Roll, Film) have managed a popularity score greater than 70%. Two of those teams (Ketchup ❌, Fries) still lost their respective Splatfests.
 * Based on data found in SplatNet 2, which hasn't been gathered since Action vs. Comedy (meaning other Splatfests aren't considered):
 * The most-attended Splatfest by that point was Action vs. Comedy, with 2,075,407 participants (globally).
 * The least-attended Splatfest by that point was Warm Breakfast vs. Cold Breakfast, with only 131,239 participants.
 * Europe and Japan became known for their winning streaks for Pearl and Marina respectively, however, Japan was the first to refer to a winning streak in-game. During the Flower vs. Dumpling Splatfest announcement, Pearl angrily complained about losing so many Splatfests in a row. Ironically, Pearl ended up winning that Splatfest.
 * In America/Oceania, which had more mixed Splatfest results between Pearl and Marina (with Pearl having a slight edge), Marina, after having lost the last three Splatfests in a row, angrily interrupted Pearl's rap after the Fork vs. Spoon results, since she was getting sick of losing.
