Hi!!! This is the URL for a very helpful websit. It is a 10,000 year calendar. If you have an obituary or a birth, marriage certificate and you want to know what DAY the date fell on, go here. http://calendarhome.com/tyc/ You can choose the month and year and it will give you the calendar for that time and you can see what day - say the 25th fell on in the year 1890 or 1943, etc. Hope it is helpful to you all.
