Launch a massive, high-contrast 240-minute countdown clock. Maintain the perfect 4-hour pace of play in golf, execute half-day deep work blocks, and smoke perfect briskets with our free 14,400-second web timer.
Two hundred and forty minutes (exactly 4 hours, or 14,400 seconds) is half of a standard workday. It is a massive block of time that governs the pacing of recreational sports, corporate productivity, and advanced BBQ techniques. Our free online 240 Minute Timer is designed to provide you with a pristine, distraction-free environment to track this massive interval accurately.
Using a phone timer for 4 hours is risky; the operating system often closes background apps to save battery, meaning your alarm might never ring. By utilizing our browser-based utility, you ensure perfect, zero-drift timing for your most important events.
Recreational Pacing: The 4-Hour Golf Round
In the world of golf, pacing is a massive point of contention.
A standard 18-hole round of golf for a foursome should take exactly 240 minutes (4 hours). Slow play ruins the experience for everyone on the course. If you are a course marshal or just trying to keep your group on track, setting a massive 14,400-second timer forces accountability. You have exactly 13 minutes and 20 seconds to complete each hole. Keeping this massive timer running ensures your group maintains the proper pace of play and avoids slowing down the entire course.
Corporate Productivity: The Half-Day Block
The standard 8-hour workday is broken. Research shows that corporate employees only execute about 2.5 hours of actual work per day; the rest is lost to emails, meetings, and distractions.
If you want to achieve elite-level output, you must utilize the "Half-Day Block." You commit to a 240-minute sprint. Lock your office door, turn off your phone, launch our massive 14,400-second timer, and refuse to break eye contact with your screen until the alarm rings. You will be astounded by what you can accomplish in 4 hours of pure, unadulterated focus. You can accomplish more in a single 240-minute block than most people achieve in an entire week.
Culinary Precision: Smoking the Brisket "Flat"
In the world of Texas barbecue, brisket is king, and timing is everything.
The 14,400-Second Bark Formation
When smoking a smaller beef brisket "flat" (the leaner cut without the fatty point) at 250°F, the most critical phase is the formation of the bark. It typically requires exactly 240 minutes (4 hours) of smoking uncovered for the rub and the smoke to combine into the perfect mahogany crust. Once this 14,400-second window closes, the meat will begin to dry out, and you must wrap it tightly in butcher paper (a technique known as the Texas Crutch). Start our massive timer the second you place the meat on the smoker grates.

This guarantees that your 14,400 seconds are measured flawlessly, even if your browser throttles background tabs. Enjoy our large, high-contrast digits and a soothing, synthesized alarm chime.
