Find the number of days, weeks, months, and years between two dates. Plan deadlines, count down to events, or track duration — free and instant.
Enter your start and end dates. The tool computes the exact number of days between them, plus the equivalent in weeks, hours, and a year/month/day breakdown. Use the toggle to include both endpoints in the count if needed.
Countdowns to an event, tracking project durations, calculating age in days, or figuring out how many work days are left until a deadline. The breakdown helps when you need human-readable durations instead of raw day counts.
All calculation runs in your browser. No signup, no upload — instant results as you change the dates.
