What Is a Shift Hours Calculator?

A Shift Hours Calculator computes your daily, weekly, and monthly working hours based on shift start/end times and break duration. It handles regular and overnight shifts and shows total hours for payroll and compliance tracking.

This calculator is useful for employees tracking work hours, HR teams managing shift schedules, and freelancers calculating billable hours. It accounts for break time to give accurate working hours.

Frequently Asked Questions

What is the standard shift duration in India?
Most Indian companies have 8-9 hour shifts (excluding break). IT companies typically have 9-hour shifts (10 AM to 7 PM or 9 AM to 6 PM). Manufacturing may have 8-hour shifts in 3 rotations.
How many hours per week is legal?
The Factories Act limits work to 48 hours per week and 9 hours per day. The Shops and Establishments Act varies by state but generally allows 48-52 hours per week. Overtime beyond this requires 2x wages.
Are breaks included in shift hours?
Breaks are typically not counted as working hours. A 9-hour shift with 1-hour break means 8 working hours. Some companies provide paid breaks (tea/coffee), but lunch breaks are usually unpaid.
How to calculate overnight shift hours?
For shifts crossing midnight (e.g., 10 PM to 7 AM), the calculator automatically handles it. Total duration = (24:00 - start) + end. For 10 PM to 7 AM with 1-hour break = 8 working hours.
What is the maximum shift duration?
Most labor laws cap shifts at 9-10 hours including breaks. Extended shifts require overtime pay. Some industries (healthcare, emergency services) have exceptions but must provide compensatory rest.
