Overview

Product summary

Review the store description, core capabilities, and common use cases.

Time Calculator Cardamon adds, subtracts, multiplies, divides, and converts durations right in Chrome. Type an expression like 5h 30m + 2h 15m and read the answer as 7 Hours 45 Minutes. It works in the side panel next to your tabs and in the address bar, runs offline, and needs no sign-in.

WHAT YOU CAN CALCULATE

Mix any units on one line: years, months, weeks, days, hours, minutes, seconds, and milliseconds. Write them as full words or shorthand (h, m, d, w). Type the operators straight from your keyboard: + to add, - to subtract, * to multiply, / to divide.

▪️ Add and subtract: 8h 15m + 45m - 30m

▪️ Multiply and divide: 90m * 3, or 3d 4h / 2

▪️ Convert: read any total as days, hours, minutes, seconds, or decimal hours
