Have you ever seen an old photo, poster or document that showed the date as, say, Friday 5 March, but no year? Did you find yourself wondering "What year was that"?
This app can tell you! It will tell you all of the years in which 5 March fell on a Friday.
You can even use it when looking at future years! For example, find all of the years that your birthday falls on a Saturday!
In summary, this app allows you to enter a day of the week, a day of the month and a month, and it will list all of the years in which that day and month fell (or will fall) on that day of the week.
