The "Days" column varies because calendar months are not the same length — 9 months spans between 273 and 276 days depending on where in the year you start.
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.
9 months is not a fixed number of days: depending on which months it spans it covers between 273 and 276 days. That is why calendar arithmetic in months is done by moving the month number rather than by adding days.
Calendar arithmetic is less obvious than it looks. Subtracting 9 months from January 1, 2026 gives April 1, 2025, while the same offset from July 1, 2026 gives October 1, 2025, a different number of calendar days later, because the months in between are different lengths. 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 — or to measure the gap between two dates you already have — use the date difference calculator.
