📅 Date Difference Calculator

Count the days between two dates

Pick a start and end date to see exactly how many days, weeks, months and years separate them. Tick the box to count the end day too (useful for booking nights, leave days or event durations).

Working days

The working-days figure counts Monday to Friday only, ignoring weekends — handy for project deadlines and delivery estimates. Public holidays are not deducted.
