Frequently Asked Questions
What happens when the result falls on a non-existent day?
If you add one month to January 31, the tool returns February 28 (or 29 in a leap year), clamping to the last valid day of the target month.
Can I add partial months?
This tool works with whole months. For partial offsets, combine it with the Add Days to Date calculator.
Does it work across year boundaries?
Absolutely. Adding 14 months to March 2024 correctly lands on May 2025.
