Ubuntu releases on a time based schedule. At the time Ubuntu was started the GNOME project had already established a regular release schedule every 6 months, usually September and March. So Ubuntu's schedule was "when GNOME releases, plus a little bit more to put it into Ubuntu."

The way it worked out is Ubuntu released on Aprils (hence the .04) and Octobers (.10). And it's been that way ever since, with the exception for 6.06, which had to be delayed until June due to some delays.

As it ends up releasing in the spring and fall fits nicely in the calendar and there's never been a need to shift the schedule.

Also worth noting: the first number is the year of the release.

The first number is the two last digits of the current year.
