I am working on the biography of a distant relative, Anna Bertschinger. The hand-written notes I got handed down from my grandfather state:
verm. 2. post trin. 1649
I understand that this refers to a wedding date, presumably corresponding to the second Sunday after Trinity, which would make it the Sunday ten weeks after Easter. (or is "2. post trin." the second /day/ after Trinity Sunday?) According to http://www.dr-mikes-math-games-for-kids.com/easter-date-tables.html?century=17, Easter Sunday 1649 was April 4th, so that would make "2. post trin." the 13th of June, 1649.
Is this calculation correct?
