How many vacation days do EPIK teachers get?

Hello there, I'm curious to know about the vacation days that EPIK teachers are entitled to. Could you please elaborate on the number of days they typically receive for their annual leave? Are there any additional days granted for public holidays or any specific circumstances? Additionally, is there any flexibility in scheduling these vacation days, or are they allocated according to a fixed schedule? I'm eager to understand the vacation policy for EPIK teachers in more detail. Thank you for your time and assistance.
