So, What's the Deal with Week Numbers?
This handy tool helps you figure out the week number for any given year, all thanks to the super popular ISO 8601 standard (it's a big deal in business and around the world!). Basically, this standard says weeks kick off on a Monday, and the very first week of the year is the one that includes that year's first Thursday. Kinda quirky, but it works!
