How is 17 months ago calculated?

Starting from today, September 24, 2026, and counting backwards 17 months, keeping the same day of the month where possible, gives Thursday, April 24, 2025. Months are counted as calendar months rather than a fixed number of days, so the result lands on the same date number in a later month. Where that date does not exist, for example the 31st in a 30-day month, it falls back to the last day of that month.
