As I work on querying fitness activities I’ve done each day and sum them by week (Fitness Software and Projects) I thought, hey, use ISO week, there are built in functions in Golang for this…
For a while I wanted the beginning day of week instead of just using something like 2023-W51. I was thinking this would be Sunday that the day is a part of. Come to find out for December: the set week starts are: 06, 13, 20, 27. I’ve obviously never messed with ISO weeks before. Dates aren’t the most fun, but learned something with Wikipedia’s help.
