Well just as the title indicates, I've heard in a game the word "土日" used and translated as "weekend", and wanting to learn the word since I realized I didn't know it yet, I checked on Jisho, but the common word given for weekend is "週末" ? Which one is more correct, and are there some specific settings or circumstances when one would be used over the other ?
In the literal sense,
週末 is a term used to refer to only Saturday because a week starts in Sunday in Japan.
土日 obviously means "Saturday and Sunday", so those word are different.
However, the meaning of
週末 depends on context.
週末 means Saturday and Sunday in most cases, however infrequently includes Friday night.
Additionally, I feel more like
土日 is a informal word, so I don't think it's a great idea to use it in a formal document. You can use
週末 in all situations.
