I made up a set of hijri calendars for which there are 7 sets of each month (each one starting on a different day of the week) so that when you know what day the new Islamic month will begin on, you can simply print off that calendar, in shaa Allah.
Included are designations for the white days, and Islamic observances (yawmul Arafah, yawmul ashurah, etc).
You can purchase this bundle of 84 templates at my TpT store
It's a great addition to a daily calendar wall display.
You can purchase them at the following locations:
