Dictionary.com has a good example: "We work from nine to five." - you leave at the beginning of the 5 o'clock hour (I'm going for casual usage here) Since our implementation of ranges is half-open the usage here is consistent with that concept. That it doesn't match BETWEEN is actually somewhat nice since you can use ranges for half-open and BETWEEN if you want to be concise with fully-closed endpoints. But it is one more thing to remember.
