Calculate how long you\'ve been together or employed. See years, months, days, traditional anniversary names, and upcoming milestone dates.
The Anniversary Calculator computes how long it has been since a significant date — your wedding, the start of a relationship, a work start date, or any other milestone. It shows years, months, and days plus total weeks, hours, and traditional anniversary names.
Traditional wedding anniversary names assign symbolic materials to each year: Paper for the 1st, Silver for the 25th, Gold for the 50th, and Diamond for the 60th. The calculator shows which material corresponds to your current and upcoming years so you can plan gifts or celebrations in advance.
The tool includes a countdown to your next anniversary, the day of the week it falls on, and a table of your next 10 anniversaries with dates, days of the week, and traditional names.
Anniversary dates are easier to plan around when the exact elapsed time and the next milestone are both visible. This calculator helps with gift planning, milestone reminders, and keeping track of long-running personal or work dates.
Years = Current Year - Start Year (adjusted for month/day) Months = Current Month - Start Month (adjusted) Days = Current Day - Start Day (adjusted) Total Days = Current Date - Start Date (in days) Total Hours = Total Days × 24
