How to use this calculator

  1. Leave "Count from" as today, or pick another day.
  2. Enter the date of the event.
  3. Optionally add the hour it starts.
  4. Read the days, hours and minutes left.

The formula

Time left = Event date and time − Count from date. Days = whole 24-hour periods. Months and years use calendar counting.

Worked example

From 2 November 2026 to 1 January 2027 there are 60 days, which is 8 weeks and 4 days, 1,440 hours or 86,400 minutes.

When to use it

  • Count down to exams, festivals and holidays.
  • Plan a wedding, trip or product launch.
  • See how long ago something happened.
