For example if we want to add 10 checks
Hebrew Chodesh:
It will add 10 new records from the start date for 10 months based on the Hebrew date. So if the start date is the 10th day of Nissan, the first charge will be for the 10th of Nissan, the second charge will be for the 10th of Iyar and so on.
Rosh Chodesh:
It will add 10 new checks starting from the next Rosh Chodesh after your start date for 10 roshei chodeshim. So if the start date is the 10th of Nissan, your first charge will be for the 1st of Iyar, the second charge will be for the 1st of Sivan, and so on.
