Time Calculator
Time calculator for adding and subtracting hours, minutes, seconds. Duration, work time, and date calculator in your toolbar. I have two engineering degrees. I can do calculus. But ask me to add up 2:45 + 3:38 + 1:52 for a client invoice and my brain just stops working. Last month I actually grabbed a piece of paper to calculate time for my timesheet. Made a mistake. Started over. Questioned my life choices. Why isn't there a Time Calculator that just works? Right in the browser? Without opening some random website? Other time calculators exist. But they all have the same problem: - You open a new tab - Type some URL - Wait for it to load - Lose your train of thought Our Time Calculator sits in your Chrome toolbar. Click, calculate, done. Maybe 5 seconds total. Add Time Calculator - Got multiple entries? Throw them in. The addition calculator handles it. Works with two entries or twenty. Just keep adding rows. Time Difference Calculator - Started at 9:15, finished at 5:42, took 45 minutes for lunch. The calculator figures out 7h 42m of actual work. I use this constantly for billable hours. Way easier than mental math. Date and Time Calculator - "What's the date 45 days from December 15?" Needed this for a contract deadline. The time and date calculator said January 29.

Get hours and minutes, decimal hours, or full breakdown. Your choice. The time worked calculator does the math instantly. If you bill hourly, this thing pays for itself in recovered hours you used to round down. - Click the icon in your toolbar - Type your input - Get your answer You can also type expressions directly: "2h 45m + 1h 30m - 15m" and the time on calculator figures it out. Pretty handy for quick calculations. Students - Calculating deadlines. Planning sleep around papers due at 9 AM. The time & date calculation stuff gets weirdly useful during finals. Travelers - Flight math is hell. Departure plus duration plus timezone changes equals confusion. The extension sorts it out. Project Managers - Sprint planning. Deployment windows. "How many work hours until deadline?" Calculate once and move on. Everyone Else - Cooking timers. Parking meters. "If I leave at 7:15 and it takes 47 minutes, when do I arrive?" Random stuff that pops up in life. - Lives in your toolbar. No navigating anywhere. - Works offline. Airport wifi being garbage doesn't matter. - Multiple formats. Type "2:30" or "2h30m" or "2.5 hours" - it understands. - Expression mode. Type "8h - 45m + 2h 15m" directly. - Keyboard shortcuts. Ctrl+Shift+T opens it instantly. How do I use the extension? Click icon, type numbers, see result. Most people figure it out in 8 seconds. Time clock calculator for shifts? Yep. Enter start, end, breaks. The time worked calculator handles the rest. Works with specific dates? Full date and time calculator. Duration between March 15 at 9 AM and March 18 at 5:30 PM? No problem. Time calculator hours or minutes? Both. Toggle precision based on what you need. Calculations happen in your browser. History stored locally on your device. We're not harvesting your work schedule.
