Maintenance planning

Hello,

I am trying to do a sheet which plots the month of each maintenance depending on its next date and the frequency. I cant seem to get my head around it!!

Can anybody help? basically I need a 1 in each of the month the maintenance will hit yearly.
so if the job was for march and the freq is 4 then i need a 1 in mar, jun, sep, dec and the rest will be 0.

Any help will be appreciated, thanks in advance!
