Here's a permanent calendar when you need to check a day, figure out what day of the week a date fell on or whatever you can find it at: http://www.calendarhome.com/tyc/ Another useful calendar is this one designed to calculate the birth date from the death date or the age at death given in months, days and years: http://longislandgenealogy.com/birth.html There are other birth date calculators including this one: http://www.progenealogists.com/birthfromdeath.htm which does the same thing and has some other links of interest. I chose these because such web sites come and go but, hopefully, these genealogy based versions will be with us for awhile.
