⚖ Disclaimer

This calculator is for informational purposes only. Overtime rules, break entitlements and pay rates vary by country, state and employment contract. Results are estimates based on inputs provided. Always refer to your employment agreement or consult an HR professional for accurate pay and hours calculations. TimeKit does not store any data you enter.

How does the Work Hours Calculator work?

Enter your clock-in and clock-out time for each day of the week, along with any break duration. The calculator totals your hours for each day, sums them across the week, applies your overtime threshold, and shows estimated gross pay if you enter an hourly rate.

Who is this useful for?

Freelancers and consultants use it to track billable hours across client projects. Part-time and hourly workers use it to verify their timesheet before submitting to HR. Shift workers — in retail, healthcare, hospitality or manufacturing — use it to calculate whether they have crossed their weekly overtime threshold. Managers and HR teams use it to cross-check reported hours against schedules quickly without needing Excel.

Does it work offline?

Yes. All calculations run locally in your browser — no data is sent to a server. Once the page has loaded, the work hours calculator works without an internet connection. Use it on a plane, at a remote job site, or anywhere with no signal. Nothing you enter is stored or shared.

How is overtime calculated?

Any hours worked beyond the standard weekly threshold (typically 40 or 48 hours depending on your country and contract) are counted as overtime. In India, the Factories Act sets overtime at twice the ordinary rate for hours beyond 9 per day or 48 per week. Always confirm the applicable rate with your employer or employment agreement.

How to Calculate Work Hours — A Complete Guide

Calculating work hours accurately matters for timesheets, freelance invoicing, payroll, and overtime claims. Whether you work fixed shifts, flexible hours, or split across multiple jobs, knowing your exact hours prevents underpayment and billing disputes. This tool calculates total hours worked, deducts break time, identifies overtime, and estimates weekly pay — all in one place.

How to Calculate Hours Between Two Times

To find hours worked between a start and end time, subtract the start from the end and deduct any unpaid breaks. For example: 9:00 AM to 5:30 PM is 8.5 hours. Minus a 30-minute unpaid lunch = 8.0 billable hours. For overnight shifts — say 10:00 PM to 6:00 AM — the calculator handles the midnight crossover automatically.

Understanding Overtime Rules

In most countries, overtime is triggered when you work beyond 8 hours in a day or 40 hours in a week. The standard overtime rate is 1.5× the regular hourly rate (time and a half), though some employers pay 2× for hours beyond 12 in a day. Always check your employment contract or local labour laws — rules vary significantly between the US, UK, EU, and other regions.

Freelancers: Tracking Billable Hours

For freelancers billing by the hour, accurate time tracking is essential for client invoicing and tax records. Enter your start and end times for each work session, deduct non-billable breaks, and multiply by your hourly rate. Keep a weekly log — most tax authorities require records of hours worked when claiming business expenses related to time spent on client work.

Frequently Asked Questions

How do I calculate hours and minutes between two times?

Enter your start time and end time in the calculator above. It will show you the total duration in hours and minutes, with the option to deduct break time. For manual calculation: convert both times to minutes from midnight, subtract, then convert back to hours and minutes.

Does the calculator handle overnight shifts?

Yes. If your end time is earlier than your start time (e.g. start 10:00 PM, end 6:00 AM), the calculator automatically treats it as an overnight shift crossing midnight and calculates the correct 8-hour duration.

How is weekly pay calculated?

Enter your hourly rate and the calculator multiplies it by your total regular hours. Overtime hours (beyond 40 per week) are calculated at 1.5× the regular rate by default. The result is a gross pay estimate — taxes and deductions are not included.

What is the difference between 8-hour and 40-hour overtime thresholds?

Daily overtime triggers when you work more than 8 hours in a single day — even if your weekly total is under 40 hours. Weekly overtime triggers when your total for the week exceeds 40 hours. Some jurisdictions use one threshold, some use both. California, for example, applies both daily and weekly overtime rules.

Pay calculations are estimates only. Tax deductions, statutory contributions, and jurisdiction-specific rules are not included. Consult your employer or a payroll professional for official figures.
