Australia

The year was 1989. I had rented an apartment in college, starting the last week of August. Rent was due the 5th of each month. Move in was first and last months' rent, plus one month security deposit.

Okay, we kind of trashed the place, we were never getting the deposit back, but this is not about that.

Last week of August, we paid three months' rent on move-in, as described above. Our lease ended after the third week of May 1990. One week later, we paid September rent. Then the rest of the months.

March 5th comes. We pay rent. I sit down and do some math. I realize that by paying a full month at the end of August on move in, then full September one week later, that the rest of the August move-in month covers the first three weeks of May, at the end of the lease. Since we'd also paid last month's rent, that was for April. Since we'd just paid March rent ... we were done paying rent.

The building manager was none too pleased when I pointed this out. I'm sure lots of college kids got fucked over this way.
