Happy Anniversary Calculator (Marriage, Relationship, Dating)

Our authentic anniversary calculator computes the exact time span in years, months, days, hours, and even minutes, for both wedding and dating milestone tracking.

Consider a Girl and Boy’s wedding date of June 15, 2015. Using an anniversary calculator on December 6, 2024, reveals they’ve been married for 9 years, 5 months, and 21 days, helping them plan their upcoming decade celebration.

Formula to Calculate Anniversary Years

The anniversary calculation formula involves:

Anniversary Years = End Date - Start Date
Total Days = (End Date - Start Date) × 365.25

For a couple who met on March 8, 2020:

Current Date: December 6, 2024
Duration = December 6, 2024 - March 8, 2020
Result = 4 years, 8 months, 28 days
