Working Days Calculator
Add or subtract working days from a date, skipping weekends.
📐 Steps day by day from the start date, counting only Monday–Friday, until the requested number of working days is reached.
The working days calculator determines the number of working days in any month, quarter, or custom date range — essential for salary pro-ration, freelance billing, project scheduling, payroll processing, and HR leave management. It accounts for weekends and configurable public holidays, and can calculate pro-rated salary when an employee joins or leaves mid-month.
📋 How to Use This Calculator
Select a month and year (or custom date range) and choose your working week structure (Monday–Friday, or Monday–Saturday). Add any holidays you want to exclude. The calculator shows total working days in the period, and a pro-ration calculator allows entering monthly salary and days worked to compute the exact payable amount. Comparison view shows working days across all 12 months of the year.
💡 Key Facts & Information
Working days in a typical month (5-day week): ranges from 20 (February with no holidays) to 23. Full year 2024: approximately 262 working days (excluding national holidays). For 6-day weeks (including Saturday): 25–27 working days per month. Salary pro-ration formula: Per-day salary = Monthly salary / Working days in month. Payable amount = Per-day salary × Days worked. Some companies use calendar days for pro-ration. LOP (Loss of Pay) calculation uses the same per-day rate. Payroll compliance: Companies Act 2013 Section 197 and Shops and Establishment Acts specify maximum working hours. Most states mandate minimum 1 weekly holiday (Sunday).
