About

Birthday Door is shut every day but one. Set your birthday and it counts down the days; on the day itself, the door opens. A tiny private ritual.

How it works

Your birthday (month-day only) is saved in localStorage under kaspirius:birthday:date. Each visit compares today to it and either opens the door or counts the days to the next occurrence. Nothing is sent anywhere.
