By ‘outside the hostel’ you can mean two things; inside the campus or outside the campus. Well, I am here to talk about both scenarios:
Inside campus
For boys, there is no deadline and they can stroll through the campus even after midnight. Many boys like taking a walk at night and listening to their favorite music. However, girls are expected to return to their hostels before midnight, or else they have to do a late entry. The warden may or may not take action against this.
Outside the campus
Students are not allowed to stay outside the campus later than 10 30. The faculty in charge may be informed in case of any rules not being followed.
