Thanks, Brendan. As I'd never heard anyone refer to 'Easter Saturday', I looked it up before posting the clue - and the ambiguity is why I included 'tomorrow - or next week'. Even though I'm a heathen, I know these things matter to some people.
Thanks, jigjag. I'm sure Brendan would be happy to share 'his' clue with you! There was a crossover of topics, comments in the two MT threads. (I started the GF one to beat the spammers and be topical at the same time.)
