2025 started on a Wednesday, meaning that week 1 of 2025 officially started on December 30, 2024.

@daniel Oh, no! That means this is one of those years where the US count differently than the rest of the world. #offbyoneerror

@proedie @daniel I think it's not. ISO week 1 is the week of the first Thursday of the year.

Though ... I believe the US week starts on a Sunday, which would make it 2024-12-29 when their week started and not the 30th

@pseyfert @daniel Oh good. So this only happens when the last day of the year is a Wednesday, not the first. Phew. 😅
