Because the tutorialspoint server is running in another time zone?

I don't think it's a timezone issue as I am specifying the dates myself and not using the servers time. Additionally, with the test data at the top of the code, using 22/04/2017 it works and yet four weeks later 06/05/2017 does not.

 

Its as though the numbers are too great.

Oops, I've realised it was a bug in the program - Fixes in bold
