About Chronia

Chronia shows live countdowns to US holidays, the seasons, times of day and any date you pick. Every countdown runs on your device in your own time zone.

Holiday dates follow their official rules (for example, Thanksgiving is the fourth Thursday of November). Season start dates use the usual astronomical date, which can shift by a day from year to year.

Who runs Chronia

Chronia is an independent website of free online tools for countdowns, dates, age and sleep. Every tool is written and checked by our small editorial team, and each page explains the formula or data behind its answer so you can verify it yourself.

How we keep results accurate

We test each calculator against hand-worked examples before it goes live, cite the sources for any rates or published figures, and review pages when those figures change. Pages show when they were last updated. This site was last reviewed on October 27, 2026.
