Hey Apeksha !
Saturday is generally considered as a half-day in most of the medical colleges of West Bengal.
Likewise, the office hours too reduce during these days.
The weekdays working hours are generally 10 am to 4 pm.
Whereas on the Saturdays, the office remains open for the students and associated people to reach out, precisely during 10 am to 2 pm.

Hope this helps.
Best Wishes !
