There's around two weeks total of holidays (spread over the entire year). There's also a vacation benefit, which typically starts at two weeks and increases the longer you stay. Big companies give more and a senior person at a large company may get 4 or 5 weeks a year. There may also be separate sick days.
It varies by employer. I get 24 days that I pick plus 9 or 10 that the company picks each year. Plus an additional 4-week block (that I pick, but has to be contiguous) every five years.
Thanks to those that replied, I learned something today.
The people that replied are likely software engineers and likely high earners in a very employee favored market.
