How to form it

Put まで after a time, place or event: 三時(さんじ)まで (until three), 駅(えき)まで (as far as the station).
Pair it with から for a range: 月曜日(げつようび)から金曜日(きんようび)まで (from Monday to Friday).
After the dictionary form of a verb, it means "until that happens": 雨(あめ)がやむまで待(ま)つ (wait until the rain stops).
The action goes on the whole time up to that point.

駅(えき)まで歩(ある)きます。

I'll walk to the station.

三時(さんじ)まで待(ま)ちます。

I'll wait until three.

After a noun, まで can also mean "even": 子供(こども)まで知(し)っている (even children know it).

Using まで for a deadline. 五時(ごじ)までに帰(かえ)る means "be home by five"; 五時(ごじ)まで means something goes on until five.

〜までにby (a deadline)
"By" a deadline: the action happens at some point before it.
