How it works
The formula behind this calculator.
remainingDays = targetDate − today
- targetDate
- The future date
- today
- The current date
Just count the days. For an annual countdown, use the same month/day next year.
Example: Today 2025-01-01, target 2025-12-25 → 358 days
Ref: Date arithmetic
Tips
- 💡 Add 1 day if the target date is the day itself and you want to count it down to 0.
- 💡 Holidays and birthdays are best tracked as a recurring annual countdown.
