Thank you, and Happy Easter to all of you!
Interesting article on how Easter is calculated and on attempts to unify the date (don't hold your breath; this has been going on since at least the 10th century):
http://www.csmonitor.com/World/Global-News/2016/0325/Why-is-Easter-so-early-this-year A change wouldn't make a big difference in the US. In Europe, where Easter is a 4 day weekend and other religious holidays based on Easter (such as Ascension Day and Pentecost ) are also long weekends, a fixed date would at least be helpful for American tourists, most of whom don't realize that these weekends are also civic holidays with everything closed down, and highways and hotels crowded.
However, I understand that Good Friday is a holiday on the U.S. East Coast. I found that out when I once made a rather large accounting error when Good Friday fell on the last day of March. The company normally received a $10M payment on the last working day of the month, so of course I recorded it. After all, it was just a normal working day in Oregon! Fortunately, my entry affected only the quarterly balance sheet reporting, so we didn't have to change the all-important income statement!
On a more somber note, and back to the ACW, Abraham Lincoln was shot on Good Friday. Of course it was a bit later in the year in 1865.
