Overview

The Wedding Anniversary Calculator tells you how many years, months, and days have passed since your wedding, and which day of marriage you are on today. It also shows the countdown (D-day) to your next anniversary, day-count milestones such as your 100th and 1,000th day, and traditional anniversaries like the silver (25th) and golden (50th) wedding anniversary. Following Korean day-counting convention, the wedding day itself counts as day 1, so the 100th-day celebration falls 99 days after the wedding. Use it to plan anniversary gifts, trips, and parties with exact dates.

Formula

Days together = (today − wedding date) + 1 (wedding day = day 1)
Elapsed time = full years, months, and days since the wedding
D-day to next anniversary = upcoming anniversary date − today
Milestone date = wedding date + (milestone days − 1)
Example: 100th day = wedding date + 99 days, 1,000th day = wedding date + 999 days

5. 5If you are not married yet, enter the planned date to see the countdown to your wedding day.

Tips

• ✔Korean convention counts the starting day as day 1, so the 100th-day anniversary is 99 days after the wedding — this calculator follows that rule.
• ✔Your anniversary falls on the same month and day every year. If you married on February 29 of a leap year, non-leap years shift it to March 1.
• ✔Traditional anniversary names include paper (1st), wood (5th), tin (10th), china (20th), silver (25th), pearl (30th), and gold (50th) — handy for gift ideas.
• ✔For big milestones like the 1,000th day or 10th anniversary, checking the D-day in advance leaves plenty of time to plan a trip or party.
