Glamorgan start at Leicestershire
Glamorgan will begin their competitive season with an LV Championship game away to Leicestershire on 5 April.
The Welsh county will play a friendly at Oxford University starting on 31 March, then five four-day matches before the limited-overs season starts.
Their opening CB40 match sees Glamorgan away to Hampshire on 7 May.
Glamorgan's annual week in Colwyn Bay has been switched from August to June, while the visit to St Helens will take place in August instead.
The county are still considering whether to switch one of the Friends Life T20 games away from the Swalec Stadium.
No venues have yet been confirmed for matches on 17 June against Warwickshire and 20 June against Worcestershire.
The move has been suggested despite an overall cutback in the number of T20 games from 16 to 10, with the whole group stage being crammed into the period between 15 June and 8 July.
Scotland will return to the Glamorgan fixture list this season in the CB40 tournament.
