31 March 1973: broadcast of sixth episode of Frontier in Space; last appearance of Roger Delgado as the Master. It turns out that the Daleks are behind it all; the Doctor is injured but he and Jo go to track down the Dalek army.

31 March 2007: broadcast of Smith and Jones, starting Season Three of New Who; first appearance of Freeman Agyeman as Martha Jones. Martha's hospital is abruptly transported to the Moon, where the Judoon are tracking down a criminal.

Three quarters of the way through the year now, and past the January-March hump; April-June will be less intense. Nine of the 26 seasons of Old Who ended in the first quarter of the year - six of them in March, including the two-episode-per week seasons of the 1980s which are of course particularly intense for Whoniversaries.

I will stop posting Whoniversaries to doctorwho and my own journal after 30 June, since I started on 1 July last year. But I would very much like to set up a permanent feed for people who want to continue seeing them. Does anyone have any ideas as to how I might do this - or better, can anyone help directly? At present the information exists only in LJ posts, but should be easy enough to extract and to update as necessary.
