Countdown Calculator
How many days, weeks and working days until a date — a wedding, a deadline, a holiday, a birthday — counted from today.
The countdown counts whole days from today (UTC midnight) to the target date; the working-day count excludes weekends.
How the countdown calculator works
The countdown counts whole days from today (UTC midnight) to the target date; the working-day count excludes weekends. A date that has passed shows as days ago.
Formula: days until = target − today

FAQFrequently asked questions
Does today count?
No — it counts the days between now and the target, so tomorrow is 1 day away.
What if the date has passed?
The count goes negative and the label switches to "days since".
Are public holidays excluded from working days?
No, only weekends; holidays vary by state.
Can I count to a time of day?
This counts whole days; for hours between two times use the time duration calculator.
Why do weeks not add up to the months?
Months have 28–31 days, so "3 months" is between 12 and 13 weeks.
Where these figures come from
- ISO 8601 — Date and time — Representations for information interchange — the yyyy-mm-dd format and the week-numbering rules used here
- US Naval Observatory — Calendars — the Gregorian leap-year rule
- US Office of Personnel Management — federal holidays — federal holidays (not applied here)
Last checked: September 2026. The Gregorian calendar rules do not change; working-day counts exclude Saturdays and Sundays only.
