Understanding Paid Weekly Offs and Holidays
Ideally, the weekly offs are paid, and companies are supposed to give 12-13 holidays (paid) in a year. So apart from the working days (when the office is working), you get paid for 52 Sundays (in a year) and 13 holidays in a year.
Salary Calculation Based on Calendar Days
Ideally, the salary is paid out for 28/29/30/31 days (calendar days of the month). We calculate the salary per day as (Monthly gross / calendar days for the month).
So, for example, if you have a gross salary of 30,000 per month, your per-day salary for the month of April/June is 30,000 / 30 = 1,000.
For the month of January/March, it is 30,000 / 31 = 968.
For the month of February, it is 30,000 / 28 = 1,072 or 30,000 / 29 = 1,035.
Leave and Salary Deduction
Usually, when the employee applies for leave, and the leave exceeds the allowable leave on a pro-rata basis, we deduct salary based on the gross per day depending on the number of extra leaves availed.
