Understanding Leave and Holiday Policies
As per the law, including what is stated in the Shop and Establishment Act applicable to your state, any holiday that falls in the middle of leave taken by an employee is considered part of the leave. Similarly, in the case of leave without pay, the intervening holiday is also considered leave without pay.
If you follow the 26-day rule, under which you divide the monthly salary by 26 to account for Sundays and then multiply the daily rate by the number of days actually worked, you would ignore Sundays anyway.
Hope that clarifies your doubt.
