This calculator calculates the date of April for any year in the range of 1900-2099. The program uses the custome restart function module so implement that somewhere within a directory and make sure to change the "from..." line in the main file.
I originally got the idea from ch 7 of the "How to think like a computer scientist: Learning with Python" book and modified it to escape textbook boredom for a bit. Make sure to create an init.py file for the Restart_Function module.
