I'm a history teacher, and I wanted to conduct a 'mock' military draft for my
students to show how the draft process would work.

Effectively, the process requires someone to pick a date and a number
randomly out of two separate barrels. (Say January 5 and 137). That would
mean that everyone with a January 5 birthday would be called up in the 137th
group.

I have an excel sheet set up with the months and days, but I need to figure
how to assign the numbers (1 - 365) to each of those dates 'randomly'.

Thanks for your help.
