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.

It's true that it varies by employer.

Here are average numbers from the Bureau of Labor Statistics: https://www.bls.gov/news.release/ebs.t05.htm

The average is just one week a year (two weeks a year past 15 years of work), well below world average.

Like most everything in the US, vacation time varies by employer. Last year I took 6 weeks not counting holidays and wfh 2-3 days a week.
