Section 35: Leave. The leave allowed to an employee under clauses (a) and (b) shall be inclusive of the day or days during the period of such leave, on which a shop or commercial establishment remains closed under sub-section (1) of section 18, or on which they are entitled to a holiday under sub-section (1) of section 24 or section 31.
This clearly means that if your Saturday is a working day, and you took leaves on Saturday, Monday, and Tuesday, your leaves to be counted shall be Saturday-Sunday-Monday-Tuesday, i.e., 4 days. I hope this clears your doubts.
If, however, you work 5 days a week and Saturday-Sunday are weekly offs, in such cases, Monday-Tuesday will be a 2-day leave. Hope your doubt was clarified.
