Pick the start date of your first sprint, set how long each sprint runs and how many you need, then read off the start date, end date and working days for every sprint in the schedule.
How to calculate your sprint dates
- Choose the start date of your first sprint.
- Set the sprint length in days, the number of sprints, and any gap between them.
- Read the generated table, then copy or download it as CSV.
Examples
Three two-week sprints starting Mon Jan 5, 2026
Start 2026-01-05, length 14 days, 3 sprints
Sprint 1: 2026-01-05 to 2026-01-18, Sprint 2 starts 2026-01-19
Add a 2-day gap between sprints
Start 2026-01-05, length 14 days, 2 sprints, gap 2 days
Sprint 1 ends 2026-01-18, Sprint 2 starts 2026-01-21
Frequently asked questions
How is each sprint's end date calculated?
A sprint spans the number of calendar days you set, counted inclusively. The end date is the start date plus the length minus one, so a 14-day sprint that starts on the 5th ends on the 18th.
When does the next sprint start?
By default the next sprint starts the day after the previous one ends, so sprints run back to back. If you set a gap, that many days are skipped before the next sprint begins.
How are working days counted?
Working days are the Monday to Friday days that fall inside each sprint's date range. Weekends are still part of the sprint length but are not counted as working days. Public holidays are not deducted.
Does the sprint length include weekends?
Yes. The sprint length is measured in calendar days, so weekends count toward the span. A two-week sprint is 14 calendar days, which is normally 10 working days.
Can I model gaps, holidays or hardening sprints?
You can add a fixed gap in days between sprints, which is useful for breaks, holidays or planning time. Each sprint uses the same length and gap, so the schedule stays consistent.
Is my data sent to a server?
No. The whole schedule is generated in your browser, so the dates and settings you enter never leave your device.
