[Remind-Fans] 5 weekly cycle on Sundays?

[Richard Sandilands]

Hi there

There are a series of local markets in my region that I want to enter  
into Remind.

On the first Sunday, there is Town A; second Sunday, Town B etc

However, *if* there is a fifth Sunday in the month, then that market  
is held in Town E. So of course not all months have five Sundays. I'm  
stuck on implementing this in Remind.

Any clues would be appreciated.
