How it works

Weeks vs days: 1 week = 7 calendar days. Adding a full number of weeks keeps the same weekday (e.g., Monday + 1 week → Monday).

Time zones: We operate on whole dates in your browser’s local time. Time-of-day and DST changes don’t affect the weekday result.

Examples: If the start date is 2025-09-02 (Tuesday), then 1 week from that date is 2025-09-09 (Tuesday).
