Dear Shweta,
An organisation can either have calendar days' leave or working days' leave.
If an organisation follows the calendar day leave policy, then any weekly off or holiday falling within leaves is added to the leave. That is,
1. EL/PL + weekly off/holiday + EL/PL = weekly off/holiday is considered as EL/PL and included in leave
2. CL/SL + weekly off/holiday + CL/SL = weekly off/holiday is considered as CL/SL and included in leave.
If weekly offs/holidays fall at the beginning or end of the leave period, however, organisations' policies either add such offs/holidays to the leave, or not, depending on the policy they prefer. But the organisation policy must be clear on this point, whichever practice is decided upon.
On the other hand, if an organisation follows the working day leave policy, then irrespective of how many weekly offs/holidays fall within the leave period, they are not counted. Only the working days falling within the leave period are counted. This is so in all types of leave. Public offs/holidays falling at the beginning/end of the leave will also not be counted as leave.
I hope this is clear.
Jeroo
