From, Until, By (から・まで・までに)

から・まで works on both time and place with no change in shape, unlike English switching between “from 6 to 7” and “from Tokyo to Kyoto” without a second thought. Japanese uses the identical pair either way.

まで means the action continues all the way up to that point, staying home doesn’t stop early. までに means the action happens once, somewhere before that point, the homework could be turned in today, it just can’t be later than tomorrow. Mixing them up is a common trap: 明日まで宿題を出してください would mean “keep turning in homework continuously until tomorrow,” which doesn’t make sense for a one-time action like handing something in.
