Days Until Date Calculator

See how many days are left until a date that matters. Pick a target date and the tool shows the days, weeks, months and working days remaining. The from date starts at today, but you can set it to any date to count between two points in time.

How to count the days until a date

  1. Pick the target date you want to count toward.
  2. Leave the from date on today, or change it to count from another day.
  3. Read the days remaining, plus the weeks, months and business days breakdown.

Examples

A month away

From 2026-01-01, target 2026-01-31
30 days, 4.3 weeks, 1.0 months, 21 business days

A date that has already passed

From 2026-06-09, target 2026-06-02
-7 days (7 days ago), -5 business days, marked as past

Frequently asked questions

How is the number of days counted?

It is the whole-day gap from the from date to the target date. The same date entered twice is zero days. A target that is one calendar day later is one day, so the count does not include the from date itself.

What happens if the target date is in the past?

The day count turns negative and the result is flagged as past. For example, a target seven days before the from date shows as -7 days. The weeks, months and business days figures go negative too.

How are business days worked out?

Business days count Monday to Friday only, skipping weekends. The from date is not counted but the target date is when it lands on a weekday. Public holidays are not removed, so adjust by hand if your calendar observes them.

Why are weeks and months shown with a decimal?

Weeks are the day count divided by seven and months use an average month length of 30.44 days, both rounded to one decimal place. They are quick approximations for planning, not exact calendar month boundaries.

Does it handle leap years?

Yes. The tool uses real calendar dates, so February 29 in a leap year is included and any leap day between the two dates is counted.

Is my data sent anywhere?

No. The calculation runs entirely in your browser and the dates you enter never leave your device.
