Hi @Anushree,
Technically all leaves with pay are excluding weekly off and holidays which means even if an employee is on leave for whole month (30 days) which includes 4 weekly off and 1 holiday then employee should be considered on leave for 25 days only.
Similarly, if an employee take leave from Saturday to Monday where Sunday is weekly off then Sunday should not be counted as leave. Hence only 2 leaves should b counted, this is a general practice indeed.
Hope that helps
