About

HH:MM TIME CALCULATOR by R. Carbonell

Designed for anyone who works with time on a daily basis  whether you're tracking work hours, scheduling shifts, managing payroll, or calculating project durations — the HH:MM Time Calculator makes working with time simple, fast, and accurate.

Traditional calculators can't handle time. They don't understand that 1 hour and 30 minutes isn't the same as 1.30. This extension was built specifically to solve that problem, giving you a dedicated time calculator that lives right in your Chrome browser, always one click away.

⏱ WHAT IT DOES

The HH:MM Time Calculator lets you add, subtract, multiply, and divide time values in HH:MM format.  Just like a regular calculator, but built for time. Type in a time, select your operation, type another time, and press Enter or = to get your result instantly.

✨ KEY FEATURES
• Add, subtract, multiply and divide times in HH:MM format
• Type any time using a period and it autoconverts — type 1.30 and it instantly becomes 1:30, saving you time and keystrokes
• Live decimal and minute conversion — simply type any time without pressing anything and the calculator immediately shows you the decimal hours and total minutes automatically
• Full keyboard support — use your number keys, Enter for equals, period or colon as separator, and Backspace to delete
• Mouse and keyboard friendly — every button works with both mouse clicks and keyboard shortcuts
• Calculation history — see your last 4 calculations at a glance
• AC to clear everything and start fresh

🎯 WHO IS IT FOR?

This tool is ideal for payroll administrators, project managers, freelancers billing by the hour, logistics coordinators, healthcare workers tracking shift times, or anyone who regularly needs to add up or calculate hours and minutes.

No more manual conversions. No more errors. Just fast, accurate time calculations at your fingertips.
