# Repeating dates

Dates repeat themselves every so often, so…

*What is the largest possible gap (in the last 200 years anyway) between repeating dates?*

##### a. Same Day + Date + Month

For example, I am writing this on Friday 2 November 2012. The previous Friday 2 November was 5 years ago in 2007, but the next Friday 2 November is in 2018, another 6 years away. Such gaps of 5 and 6 years are very much the norm.

On rare occasions, it can be much more than that.

*So, what is the largest possible gap between dates with the same day of week, day of month and month, similar to those above?*

##### b. Same Day + Date

For example, the previous instance of a Friday on the second day of the month was in Friday 2 March 2012, a gap of 8 months between then and now.

Again, it can sometimes be rather more than that.
