How to count days between two dates

Pick a start date and an end date. The calculator returns the total number of days, a weeks-and-days view, and a full calendar breakdown in years, months, and days. From January 1 to December 31, 2026 is 364 days, or 11 months and 30 days.

Days, weeks, months, and years

Different tasks need different units. Counting down to an event? Use total days. Planning in sprints? Use weeks. Tracking tenure or age-like spans? Use the calendar breakdown, which accounts for varying month lengths and leap years.

  • Countdowns to events and deadlines
  • Notice periods and contract terms
  • Tenure, anniversaries, and milestones
  • Gaps between any two dates

Need workdays only?

To exclude weekends and holidays, the Business Days Calculator is on the way. To move a date forward or back instead of measuring a gap, use the Date Calculator.
