# Duration Arithmetic Across Months When adding or subtracting months to a date, the result depends on the day of the month you start with. If you add 1 month to January 31st, you get February 28th (or 29th in a leap year) because February doesn't have 31 days—the calculation "clamps" to the last valid day of the target month. This can create surprising results: adding 1 month to January 31st gives February 28th, but then adding another month gives March 28th, not March 31st, because you're now starting from the 28th. To avoid these edge cases, it's often safer to work with specific day-of-month values (like "first of the month") or use day-based arithmetic instead.
