Frequently Asked Questions
Which date format do you use?
We use YYYYMMDD (ISO standard). Other formats (MMDDYYYY) yield different palindrome dates.
Can there be multiple palindrome dates in a year?
Rarely. Some years have none, others have one or multiple depending on the format.
Does leap year affect palindrome dates?
Only insofar as February 29 exists—but the palindrome property depends solely on digit arrangement.
How far ahead will the calculator search?
It searches day-by-day without a fixed limit. Palindromes become less frequent in distant future centuries but are still found.
