Ncp calculation in pf returns - employee is absent for half day - gross salary for 29.5 days is to be taken into consideration?

If an employee is absent for half a day, i.e., in a month of 30 days, he has worked for 29.5 days. How should the NCP value be calculated in PF Returns? In this scenario, should the gross salary for 29.5 days or the gross salary for 30 days be taken into consideration?

A full 30 days is to be considered. NCP stands for the non-contributory period, and if the employee has taken a half-day leave, it would be counted as present.

Thank you, sir. Should the gross salary value also be filled in as the 30-day value?
