Formula
Days = Target Date − Today
This calculator counts the number of days from today until your target date. Set the year to any year between 2024 and 2100.

- Enter the target Day and the target Year.
- Read how many Days Until and Weeks remain.
- If the date passed this year, pick next year.
Example
If you set the date to December 25, the calculator counts the days from today until that date. The count starts tomorrow, so a target of tomorrow shows 1 day.
Frequently Asked Questions
Does this include today?
No, the count starts from tomorrow. If your target date is tomorrow, the result is 1 day.
What if the date already passed this year?
Set the year to next year (or any future year) and the calculator will count the days to that exact date.
Does it account for leap years?
Yes, the calculation uses actual calendar dates and correctly handles leap years.
Can I count days to a date in 2028 or later?
Yes, set the year field to any year from 2024 to 2100 and the calculator will count the exact days.
Why does the count change depending on the time of day?
The calculation is based on the current calendar date, so the number of days remaining only drops when the date rolls over to a new day, not gradually through the day. This means the result stays the same whether you check it in the morning or the evening. If you're crossing time zones, the count reflects the date where the calculation is run.
How many days until my birthday or a recurring holiday next year?
Just enter the month and day of the event and set the year to whichever upcoming year it falls in. For a recurring date like a birthday that has already passed this year, choose next year so the countdown points to the right occurrence. The tool then counts the exact days, automatically including any February 29 that lands in the range.
