Time is weird. We pretend it’s this rigid, mechanical thing that ticks along at a steady pace, but anyone who has ever stared at a microwave or sat through a boring meeting knows that’s a lie. If you’re asking how long until 5:45, you’re probably in one of two camps. Either you’re counting down the seconds until the workday ends, or you’re panicking because you’ve got a dinner reservation or a train to catch and the minutes are vanishing faster than your morning coffee.
Calculating the gap is easy math, sure. If it’s 4:30 PM, you’ve got an hour and fifteen minutes. If it's 5:15 AM and you're staring at the ceiling, you have thirty minutes of "rest" left before the alarm ruins your life. But the technical answer is rarely why we’re checking. We check because of "time pressure," a psychological phenomenon that actually changes how our brains process logic.
The math of how long until 5:45 (and why your brain struggles)
Let’s be real. Our brains aren't naturally built for the sexagesimal system—that’s the base-60 system the Sumerians handed down to us thousands of years ago. We like base-10. We like things that end in zero. When you try to figure out how long until 5:45, your brain has to jump through hoops. You calculate the minutes to the next hour, then add the remaining 45. It’s a multi-step process that feels surprisingly heavy when you’re tired.
If it’s 3:52 PM, you don't just subtract. You think: "Okay, eight minutes to 4:00, then an hour to 5:00, then 45 minutes." Total? 1 hour and 53 minutes.
It's basically mental gymnastics.
Chronostasis and the "Frozen" Clock
Ever glanced at a clock and thought the second hand stayed still for way too long? That’s called chronostasis. It’s a literal glitch in your visual perception. When your eyes move rapidly from one point to another (a saccade), the brain actually nixes the blurred data during the move and "backfills" the gap with the first steady image it sees. So, if you look at the clock to see how long until 5:45, the first second you see actually feels like it lasts much longer than a second.

It’s not just you. The clock is literally playing tricks on your consciousness.
Why 5:45 is the ultimate "Golden Hour" for productivity
In the world of logistics and workplace culture, 5:45 PM is a fascinating threshold. It’s not quite the 5:00 PM "standard" exit, and it’s not yet the 6:00 PM "overachiever" mark. For many, it represents the "buffer zone."
According to productivity experts like Laura Vanderkam, author of 168 Hours, how we spend these specific transitional periods defines our work-life balance. If you're asking how long until 5:45, you might be hitting that late-afternoon slump where the prefrontal cortex—the part of the brain responsible for complex decision-making—starts to flag.
- The "Just One More Thing" Trap: You think you have time to start a new task. You don't.
- The Commute Calculation: Most people who aim for 5:45 are trying to dodge the peak 5:00 PM traffic or catch a specific 6:00 PM train.
- The "Dead Zone": Between 5:00 and 5:45, very little real work happens in corporate America. It’s mostly posturing or cleaning up emails.
Honestly, if you find yourself constantly checking the time, you're likely experiencing "time scarcity." This is a mental state where the fear of running out of time actually lowers your effective IQ. You become less creative and more reactive.

Time zones and the global 5:45
We live in a hyper-connected world. While you're wondering how long until 5:45 in New York, someone in London is already deep into their evening, and someone in Tokyo is waking up for the next day.
Standardization didn't even exist until the railroads forced it on us in the 19th century. Before that, every town had its own "local noon" based on the sun. Can you imagine the chaos? Trying to coordinate a meeting for 5:45 when "5:45" meant something different ten miles down the road would be a nightmare. We take the synchronization for granted, but it's a very recent human invention.
Mastering the countdown: Actionable steps
Stop just watching the numbers change. If you have a specific amount of time left before 5:45, use a "Time Block" strategy rather than a "Countdown" strategy.
First, look at the actual minutes remaining. If it’s more than 30, pick one "low-drain" task. This isn't the time for a deep-dive project. It's the time for filing, clearing your physical desk, or prepping your "To-Do" list for tomorrow.
Second, set an external alarm for 5:40. This allows your brain to stop the constant "scanning" of the clock. When you know an alarm will tell you when you're five minutes out, your brain releases the "time pressure" and allows you to actually focus on the present moment.

Finally, recognize the "Transition Ritual." Instead of working until the very last second, use the final ten minutes before 5:45 to mentally close the door on your current state. Whether that's closing browser tabs or just taking a breath, it bridges the gap between "on the clock" and "my time."
Checking how long until 5:45 is usually a sign that you're ready for whatever is next. So, stop the mental math. Set the alarm. Breathe. The time will pass whether you stare at the clock or not, but it'll feel a whole lot faster if you stop watching the pot boil.
To make the most of the remaining time, identify the single most annoying task you've been putting off all day—something that takes less than ten minutes—and do it right now. By the time you finish, the clock will be significantly closer to your goal, and you'll have a win under your belt before the day turns over.
