Can My Former Employer Count Sundays and Holidays in My Notice Period?

Hi, I have recently switched jobs. My previous company had a 3-month notice period, of which my current company bought 1 month. Of the 2 months' notice period remaining, I served about 1 month and 5 days. After this, I adjusted the total PL available to me, which exactly matched the number of balance working days available in my notice period.

During the settlement, the company has indicated a recovery from me of 7 days, citing the Sundays/Holidays in the notice period as well, not just working days! Is it even allowed? Can they include Sundays/Holidays in the notice period calculation to deduct money?

Sundays, holidays, or days off will be provided if an employee works six days a week, with the seventh day (Sunday) considered the weekly day off. Therefore, the weekly offs are also paid days for working continuously for six days or 48 hours. When you don't work, you will not be eligible for any holidays or weekly offs.
