GeekDad Puzzle of the Week – Easter Anniversary Dates

Geek Culture

This past Sunday was a very fun day in our house. Not only was it Easter Sunday, with an egg hunt and a great service at our local house of worship, but it was also our 12th wedding anniversary. Yes, that’s right, my wedding anniversary date is 4/20. Please note that the only reason that particular date was chosen was that it was the date when the adorable bed & breakfast at which we were wed was available.

In any case, our first wedding anniversary back on April 20, 2003, also fell on an Easter Sunday — much to our chagrin, as we wanted to “celebrate big” but couldn’t, as most restaurants were closed. More recently, in 2007 and again in 2012, there was a Friday the 13th in April — on the Friday immediately before our wedding anniversary.

Thinking about these date anomalies around our wedding anniversary led me to this week’s GeekDad Puzzle of the Week: Since the Gregorian Calendar was established in October 1582, how many times has my wedding anniversary date of April 20th fallen on either Easter Sunday or in an April that also contained a Friday the 13th?

As always, please send your submissions into GeekDad Central. All correct (or reasonably correct) responses received will be entered into a drawing for this week’s prize: a $50 Gift Certificate from the fine folks at ThinkGeek.

Thanks, and happy puzzling!
