The answer at the top of this page is worked out in your browser against today's date, so it is always current — there is no cached "today" baked into the page.
120 days is 17 weeks and 1 day. The weekday always shifts by 1, so a Monday start lands on a Tuesday.
Calendar arithmetic is less obvious than it looks. Subtracting 120 days from January 1, 2026 gives September 3, 2025, while the same offset from July 1, 2026 gives March 3, 2026 — the same span, but landing on a different weekday. The table above lists the result from the 1st of every month of 2026 so you can read off the pattern directly.
For an offset from a date other than today, enter it in the start-date box above. To measure the gap between two dates you already have, use the date difference calculator.
