Countdown Day Clock
Live countdown to Christmas, Halloween, Thanksgiving and more — or any date you pick — down to the second.
What Is the Countdown Day Clock?
The Countdown Day Clock shows a live days-hours-minutes-seconds countdown to any of 19 built-in holidays — Christmas, Halloween, Thanksgiving, Easter, New Year's and more — or to any custom date like a birthday or vacation. Movable holidays are calculated correctly each year: Easter via the church calendar formula, Thanksgiving as the fourth Thursday of November, Mother's Day as the second Sunday of May. A sortable list shows how far away every upcoming holiday is.
How It Works
Pick a holiday from the list (it automatically counts to the next occurrence) or switch to Custom Date and enter your own with a label. The clock ticks live; the table below shows all upcoming holidays — click any row to count down to it.
When to Use It
Use it for the classic 'how many days until Christmas?', school countdowns, wedding and vacation countdowns, or a live clock to New Year's Eve.
