About this calculator

Years celebrated since an anniversary date, plus days to next, plus the traditional and modern gift suggestions for that year. Standard US wedding anniversary gift list (Hallmark): paper (1), wood (5), tin (10), crystal (15), china (20), silver (25), pearl (30), ruby (40), gold (50), diamond (60).

Frequently asked

Where do gift suggestions come from?+
US tradition: 19th century Victorian list (1, 5, 10, 25, 50). Hallmark filled in others in the 1950s. Britain has its own list; Catholic and Lutheran traditions differ.
Why do "traditional" and "modern" differ?+
Modern list (1937) added options for years that didn't have one and updated some (e.g., year-1 paper traditional → clocks modern).
Can I use this for non-marriage anniversaries?+
Yes — the math works for any "since X date" calculation. The gift list is wedding-specific but you can ignore it.
What about month-anniversaries?+
Month-anniversaries (e.g., "1 month dating") aren't wedding-list standard. Use months-between-dates for those.
Why does the "years" sometimes look off by one?+
Because the calendar year minus birth year is N until the anniversary occurs that year — at which point it becomes N. The calculator handles both pre- and post-anniversary correctly.
