The news service transmits to Yorkshire, Lincolnshire, northwestern Norfolk and parts of Derbyshire and Nottinghamshire areas of England.

It is produced and broadcast from ITV Yorkshire's Leeds studios with district reporters and camera crews based at newsrooms in Hull, Lincoln, Sheffield and York.

Freesat viewers in Mansfield, Ashfield, Newark and Bolsover receive Calendar East on channel 103 as default via those areas postcode.

In some (but not all) areas of North Yorkshire viewers have their aerials point to Bilsdale TV transmitter that broadcasts ITV News Tyne Tees from Gateshead, however most viewers in the county point their aerial to the Emley Moor or Oliver's Mount Transmitter to watch ITV News Calendar.

Viewers in Scarborough and some in Filey receive ITV News Calendar from the relay transmitter at Oliver's Mount.

At the same time, Yorkshire Television inherited the Anglia news offices in Grimsby and Hull and opened a further newsroom in Lincoln.

For over twenty years from June 1990, Calendar was produced and broadcast from a dedicated news centre and studio facility based in a converted roller rink opposite the main complex on Kirkstall Road.

The final sub-regional editions of Calendar aired on Wednesday 18 February 2009, with a new pan-regional programme launching the next day.
