In Holland some government organizations use Jan 1st as 'unknown birthday' and others use June 1st. Also provides hours of fun for the whole family!

- poizan42 7y agoIn Denmark we use Jan 1st too. That turned out to be a problem because our personal identification numbers (CPR-numbers) contains the birthdate, and suddenly we started running out of them for Jan 1st some years. The solution was to remove the checksum requirement (it was a weighted modulo 11 checksum), which is still sometimes causing problems with software that tries to verify it using the old rules. But for some reason that was thought to be better than adding another digit, maybe because it "only" requires every piece of software working with CPR-numbers in existence to be updated but not the data storage...
- sobani 7y agoAh yes personal identification numbers (BSN in Holland) don't 'spark joy' either. In Holland every resident gets a unique BSN. So you can use it to uniquely identify a person. Except if you also have to deal with asylum seekers, because they get a slightly different kind of number which will be reused after the asylum seeker is granted/denied residency.
