How is the thirteenth month calculated?

It adds earnings for a block of up to four months and divides the total by twelve.

Does it work if I worked fewer than four months?

Yes. Change the months worked in the period to get a prorated estimate.

You can add them as other period earnings if your payroll treats them as part of the base.
