We are glad to hear from you, especially if you have found a date that needs correcting.
When to write to us
- Correcting a date or a fact: include the page link, the date you believe is right, and its source if you have one.
- Suggesting an occasion or calculator: tell us what you were looking for and could not find.
- A technical problem: tell us your device and browser, and exactly what happened.
We read every message, and date corrections are handled first.
