A LITTLE CLARITY

How are weeks and sprints calculated?

ISO week rules

ISO weeks run Monday–Sunday. Week 01 contains January 4 (the first Thursday). An ISO year has 52 or 53 weeks.

2027-01-01 → 2026-W53
The date is in 2027, but the ISO week year is 2026.

Sprint cadence

Sprints start on the anchor date and run consecutively, including weekends and holidays. The end date is inclusive; the next sprint starts the following day. Dates before the anchor are not started.

Monthly sprints keep the anchor day of the month, using the last day when necessary. January 31 is followed by the last day of February, then March 31.

Dates, progress and export

Today uses your device’s local date. Progress includes elapsed time today; remaining days include today. Release dates are relative to sprint end. ICS uses all-day events across time zones.
