About WhenIsThe
WhenIsThe answers one question — when is it? — for the things people actually wait for: game releases, movie premieres, rocket launches, race weekends, sales, and holidays. Every page has a live countdown, the exact date in your timezone, and the context that a bare date can't give you.
How the dates stay correct
Nothing here is typed in by hand. An automated pipeline rebuilds the entire site every day, pulling each category from an official or authoritative source. When a date moves — a game is delayed, a launch slips, a schedule changes — the page updates within a day, automatically. Each page's footer shows when it was last rebuilt.

Corrections
Spotted a wrong date? It usually means the upstream source hasn't updated yet — pages refresh daily. If something still looks off after a day, the source itself likely changed format, and the pipeline will flag it on the next run.
