FAQ
How do I subtract days instead of adding?
Enter a negative number in the days (or weeks) field. Subtracting 30 days is the same as adding −30, and the weekday result updates automatically.
Does it handle leap years?
Yes — arithmetic is done on real UTC timestamps, so 29 February, century non-leap years, and year boundaries are all handled exactly.
Why combine days and weeks?
Common deadlines are quoted either way — 90-day return windows and 12-week training plans are both one-step calculations instead of mental conversion.
