Shared links pin the reference date so the result is reproducible. Dates are in the URL; avoid sharing private milestones. Parameterized results are marked noindex.

How this calculator works

Subtract the reference date from the target date, then divide the elapsed calendar days by seven. The starting date is day 0. Full weeks round down, and leftover days are shown separately. The exact-week result is rounded to two decimal places.

Calculations use calendar dates, not local clock timestamps. Changing clocks for daylight saving does not turn a seven-day date interval into a shorter or longer week. Supported years are 1000–9998, and results must stay within that range.

Worked examples

A deadline 15 days away

From 2026-11-07 to 2026-11-22 there are 2 full weeks and 1 day (15 elapsed days). Counting both dates gives 16 calendar dates.

A target that has passed

With reference date 2026-11-07 and target 2026-10-31, the target was 1 week ago. The signed difference is -7 days, not a positive countdown.

The target is today

When the target and reference dates match, the countdown is 0 weeks and 0 days. This is a date-based result, not a timer to a particular hour.

Plan with full weeks, not just rounded numbers

A 13-day countdown contains only one full seven-day week plus six days. Rounding it to two weeks can overstate your available time. For a deadline tied to a particular hour or location, confirm that time separately.

FAQ

Why can today differ between time zones?

At the same instant, one location may already be on the next calendar day. Choose a time zone and press Use today to refresh the reference date. Once you enter two dates explicitly, daylight-saving changes do not alter their calendar-day difference.

Are weekends and holidays included?

Yes. These are calendar-day calculations. They do not count business days, skip holidays, or adjust a result to a working day.
