About The Ultimate Calendar Project

Tags List <- Find holidays & fictional birthdays for your fandoms/interests/birthday

Hello! My name is Kaius and I am extremely dissatisfied with existing collections of novelty/lesser-known holidays and fictional birthdays.

All posts will be tagged using a 4 digit format to make it easy to find a specific day. For example, #0101 is January 1st and #0514 is May 14th.

(Fictional) holidays, fictional (and toy) birthdays, and curated Tumblr calendar posts will frequently be reblogged. Here are related blogs I recommend checking out (light theme warning)!

All tags and keywords will work if you use the search bar on the left!

This blog will run for as many years as possible. There are all kinds of surprises scheduled! @reblogginganyway is an extension of this project. It reblogs posts in the wrong year. Masterlists: Pop Culture Holidays Masterlist | Fictional & Toy Birthdays Masterlist

Mega Man Reminder: Roll Day is today (06/06 12:00 JST; 06/05 11:00 EDT), so let’s give our favorite li'l lab helper lots of love!

(No this isn’t an official Capcom thing. It’s just a Japanese date/syllable thing. Like “Rock Day” (06/09 = ro/ku). 6 = ro; 6/6 = ro/ro = “roru” = Roll.)
