Add Months to Date

Add Months to Date

Add or subtract a specified number of months to/from any date.

How it works

This calculator adds (or subtracts if negative) months to a date while intelligently handling:

• Year transitions: Automatically adjusts the year when crossing year boundaries
• Month-end dates: Handles edge cases like adding 1 month to January 31 (becomes February 28/29)
• Leap years: Correctly accounts for February 29 in leap years

Use cases

• Subscription renewals (monthly, quarterly, annual)
• Contract end dates
• Payment due dates
• Project milestone planning
• Financial forecasting
• Recurring event scheduling

Examples

• January 15, 2025 + 3 months → April 15, 2025
• January 31, 2025 + 1 month → February 28, 2025
• January 31, 2024 + 1 month → February 29, 2024 (leap year)
• November 15, 2025 + 3 months → February 15, 2026
• May 20, 2025 - 2 months → March 20, 2025
