Day Counter
Count the days until (or since) any date, including a live countdown.
Counting down to an event, or counting up from a past date — birthdays, anniversaries, deadlines, milestones — this gives the exact day count either direction.
Countdown vs. count-up, same calculation
Whether a date is in the future or the past, the underlying math is identical — this simply labels the result as "until" or "since" based on whether your target date has already happened.
Frequently asked questions
Does today count as day zero or day one?
The count reflects full calendar days between today and your target date — check the specific result against your intended use case if exact day-zero conventions matter for your purpose.
Can I use this for recurring countdowns, like every anniversary?
You'd need to update the target date each year, since this calculates against a fixed date you enter rather than a recurring pattern.
