The county season gets under way on Sunday as champions Yorkshire start the defence of their title against promoted Worcestershire at New Road.
Hampshire begin life back in Division One at home to Sussex, while Middlesex host Nottinghamshire and Durham face Somerset at Taunton.
In Division Two, last season’s bottom club Leicestershire, without a County Championship win for two years, entertain Glamorgan, while Northants take on Gloucestershire.
Surrey, with former England batsman Kevin Pietersen back in their ranks, begin their bid for promotion against Glamorgan at Cardiff on 19 April.
Like last season, most Championship games will start on Sundays, with the majority of T20 Blast group games on Fridays, beginning on 15 May.
One-Day Cup group games will all take place between 25 July and 19 August, with quarter and semi-finals to follow ahead of the final at Lord’s on 19 September.
The BBC will again have commentary on every day of every county match this summer, via the BBC Sport website and BBC Sport app on desktop, tablet and mobile.
