I found this universal calendar generator which might be useful for looking up which exact days might be referred to in old documents. I found an obituary in the Times, 9th Feb that reported that an uncle of mine had passed on "Sunday", by using this I was able to calculate the date to the 6th of Feb, 1949. Hope it helps!

As one brickwall falls another bugger puts one up!!!!!!!!!!!!
As well as working out the day of the week for a particular date, I've found it very useful in interpreting dates before the calendar change (1752) and also in working out regnal years often found in old deeds.
