Fix credit card expiration date

[antfroger]

Description

Fix credit card expiration date.

The generated expiration dates were in date/month format when they should be in month/year format.
Also, the month generated was between 12 and 30 when it should have been between 1 and 12.

Are you trying to fix an existing issue?
