If your establishment is a factory then the holidays or weekly off days coming in between two leave days will be counted only as holiday or weekly off days, as the case may be, and not as leave days. This is because the earned leave/ PL under Factories Act is calculated based on the actual days present in the factory and not on the basis of pay days. At the same time, there is no such treatment with regard to treatment of PL under Shops Act. besides, there may be casual leave available to employees in commercial establishments. There can be a generally accepted norm for sandwiching of holidays and accordingly, holidays and weekly off days coming in between two Casual Leave days are treated as holidays/weekly off days and holidays/ weekly off days coming in between two PLsor sick leaves shall be treated as PL or SL, as the case may be.
