They start whenever the previous season starts. There seem to be a couple of 1/14 seasons a year. Both that and the 3/7 league look to be heading for spring conclusions.
The current 7/14 season (about 13 months old now) has only two outstanding games, but then they could take a few more months to resolve.
And the 14/21 is only awaiting a few more games, but how long they'll take is another thing entirely.
