Anyone can tell you about how many shopping days there are until Christmas, or what costume they’re planning for Halloween, but how many people know when First Contact Day is, or what day of the week the Wookiee Life Day falls on?

Thank goodness, then, for Atlas Obscura’s first calendar. With the help of suggestions from our readers, we’ve assembled over 75 pop culture holidays to help you celebrate your favorite fictional occasions, with birthdays of famous characters from Rory Gilmore to Harry Potter, and important days in fiction from Bloomsday to Judgement Day. While the calendar is far from comprehensive, we’ve put together a collection of some of the greatest pop culture occasions (that we can put a date to) anywhere this side of Middle Earth.
