Shift calendar display whos is working

[fyrfighter]

Hello everyone, hopeing this is the correct place to place this, if not I apologize.

 

I dont have a script, but here is what I hope to accomplish.

 

There are 4 crew working, each works two days, then two nights then gets 4 off.

Ex..

A platoon works 17th day, 18th day 19th night, 20th night then gets 4 off

B platoon works 19th day, 20th day, 21st night, 22nd nght then gets 4 off

C platoon works 21st day, 22nd day, 23rd night, 24th night then gets 4 off

D platoon works 23rd day, 24th day, 25th night, 26th night then gets 4 off

A platoon works 25th day, 26th day......

This schedule revolves like that for the entire year. (if A is working days, then D is working nights etc)

 

I wanted to know if anyone could help me create a script that displays which crew is currently working, a script example that knows it is the 23rd and outputs "D platoon is on Duty"

 

If anyone understands this and can help, please let me know.

Thanks
