まで (MADE) can be translated as "until" or "as far as," and is used to set a limit in time or space. It is often associated to the particle から (KARA), which in contrary defines the beginning to build the structure "from... to..."
Mori made arukimashita.
I walked as far as the forest.
Gyuuniku wa doyoubi made okaidoku desu.
Beef is on special offer until Saturday.
Use the particle まで (MADE) to extend the limit, to give the idea that one can go beyond the limit of what could initially be thought.
Kono omise wa nichiyoubi dake de naku shukujitsu made aite iru.
This shop is not only open on Sundays, but also on holy days.
まで (MADE) defines an excessive idea in phrases such as "to go as far as doing something".
Kare wa sutoresu de shigoto o yameyou to made kangaete ita.
He (even) thought about quitting his job due to stress.
It can also be used negatively to say that one doesn't have to go that far, there is no need to. まで is then placed after a verb and is followed by も ない (MO NAI).
Maeda san ga shiken ni goukaku shita ka wa kiku made mo nai.
There is no need to ask whether Mr. Maeda passed the test.
