Do international teachers really only work 180~190 days a year?

I haven't worked a day in my life yet so I don't know how this "employment" thing goes, but what I do know is that I want a job with good work-life balance. I've been thinking of becoming a Math/Physics teacher, since I think I'd enjoy teaching, and the more I research about international teaching, the better it seems. The statistic that caught my eye the most was the number of working days teachers have, and how low it seemed.

According to a blogpost I found, most people in my country work around 245 days, or around 1940~1960 hours, a year. A quick google search suggests that it's about the same in the US.

In contrast, according to this reddit thread, it seems like most international teachers only work around 180~190 days a year, including training days. That's an additional 50~60 days of rest!

Combined with the free housing, the slight salary bump compared to domestic teaching jobs, being partly paid in the relatively stronger US dollar, being able to send your kids to a private school for free, etc etc, this deal seems too good to be true...

In your experience, do you actually only work 180~190 days a year? How many hours do you work each day? Does the work you end up having to take home make up for the 50 day difference?
