It's tough to give a complete answer because it's unnecessarily complicated. I get Family/Personal Leave I can use for anything, but I'm more likely to use for things like dentist appointments than vacation and only take a couple of hours at a time. I think it comes out to about four days (I think the exact count is 32 hours of family/personal and 64 hours of sick leave).
Then I get four hours of vacation time for every pay period (half month) worked. I've worked three months, so I get about 24 hours (so three days). After a year, I'll have about a week. I think 190 hours (23 days or so) can roll over so that's a sort of maximum I can burn all at once (if I do the math correctly, that means I have to take a vacation at least once every two years or else I lose time). Of course, I can combine it with Family/Personal for a little more time.
Overall, it adds up to a decent amount if I do it right, but it's overly bureaucratic and can be inflexible at times. My personal view is that, if I get my work done, nobody should care how many hours it took. Since I get paid a salary, I don't even like the fact that my clients get billed for my time either. If I'm prepared and doing a good job, that should be the end of the discussion regardless of whether I work 20 hours a week or 60. But it's a government job, so they don't like that. I'd also point out that, in my kind of job, there's no way I can get away with taking off 23 days in a row from work because there are things that'll crop up that are too important.
