Whether you call them your golden hours or peak productive work time, or biological prime times, these are when we have the most concentration and energy. As such, we shouldn’t waste these hours. Instead, we should spend them on our most important and challenging tasks. But, before we get there, we first need to identify when you’re actually the most productive.

The most productive hour, day, week, and month of the year.

You likely already know when your most productive time is. For example, I’m a morning person, and wake-up at 5:15 am every day. Because of this, I’m more alert in the A.M. But, I also have also worked with people who are night owls, and forcing themselves to wake-up as early as I do would be counterproductive.

However, after analyzing 1.8 million projects and 28 million tasks gathered from Priceonomics customer Redbooth, says that the most productive time of year is at 11 am on a Monday in October.

That timeframe is extremely specific, but they also found “that most people don’t really get going until 7 am (a typical start time). The study shows that after 5 pm (typical finish time), work quickly tapers.”

However, the “percentage of tasks completed (9.7%) peaks at 11 am — just before the typical person takes lunch.” The data has shown that productivity takes a hit between 11 am and 1 pm, “and after 1 pm, productivity never quite returns to its peak.”

“The highest percentage of tasks (20.4%) are completed on everyone’s favorite day of the week: Monday,” Priceonomics reveals. “Tuesday (20.2%) is just behind — and after that task completion perfectly tapers off as the days progress toward the weekend.” Fridays are “nearly 20% less productive than Monday.”

“We complete far more tasks in the latter months — September (8.8 percent), October (9.5 percent), and November (9 percent) — than in the earlier months,” notes the post. “We only complete 7.2 percent of our yearly tasks in January,” The reason?

Priceconmics suspects that it “maybe because the early year is typically for setting goals, not completing them — and as we near year’s end, we’re struggling to get everything done.” You have to learn how to work smarter — not harder.

How to find your most productive hours.

Hopefully, the data from Priceconomics can be of use. For example, instead of scheduling a meeting on Monday mornings, you do that on Friday afternoons when most of us aren’t as productive.

But what if you want to find out when you’re most productive? Well, here is a simple process that can help you figure this out.

Choose a time tracking period.

The first step you need to take is to determine when you want to start tracking your time and for how long. Some suggest that you can get away with just tracking your time for a week. But I disagree. The longer you follow your time, the more accurate of a picture you’ll have. Ideally, you should do this for 30 days.

Get the right tools.

You can honestly stay old school and use a pen and paper for this activity. You could also use a notebook or index cards. Other options would be creating a spreadsheet (or this one from Chris Baily) or premade worksheets like the 168 Hours Timesheet.

If you prefer to go digital, you may want to try out time tracking tools. Some of the best available are RescueTime, Clockify, Toggl, or ATracker — and of course, Calendar.

Maintaining your time log.

Here’s the moment you’ve been waiting for, actually tracking your time.

Jeremy Anderberg writes that there are two necessary frameworks for tracking your time. The first tracking is using the time of day. If you go this route, “you’ll write down your activity for a set chunk of time, say 9–9:15 am. Set a timer for every 15 minutes (at first, at least; it can be longer as you’ve gotten into it), and take a quick second to jot down what you’ve been doing.”

The second is by the task. “With this method, you’ll go about your day and activities as normal, and simply write down what time you change tasks and start something new,” explains Anderberg.

Jeremey suggests that you try both out and see what works best for you. “For my first few days of time-tracking, I did so by the task. I’d write down, to the minute, when I started and stopped doing something and moved on to a new activity.” For him, this helped “figure out how long things actually took, and how my day was naturally being structured

“After that, I went into tracking by time increments, which is more useful for planning purposes, understanding what times of day you’re more likely to waste time, how to structure your breaks, etc.,” he adds. “Another benefit is that when you have a timer to “remind you to write down what you’ve been doing, it re-focuses you if you’ve gotten off track.”

Regardless of which approach you take, there are some essential things to keep in mind:

  • Be honest and consistent.
  • Record your activities in real-time.
  • Note when you start and end an activity, as well as the duration.
  • Be meticulous and include as many details as possible. For instance, instead of just writing done “working,” record the specific thing that you were doing. But, you don’t have to be perfect.
  • Don’t just focus on your workday. Create categories and subcategories for home, family, social, commuting, and health and wellness.
  • Make sure that you write down how you feel for each activity.
  • Leave room for additional notes like what interrupted you or if a task took you longer then expected to complete.

Chris Bailey, the author of “The Productivity Project,” also suggests that you eliminate factors that may affect your productivity, such as caffeine, diet, waking up without an alarm, or staying up too late. He also recommends keeping a log of your energy levels every hour.

After you’ve done this for around month, go ahead, and analyze your data. Pay close attention to patterns — primarily when there’s a surge or dip in focus or energy. For most of us, because of ultradian rhythms, this would be after working for 90 to 120 minutes.

You should also be on the lookout for how much time you’re dedicating to low, medium, or high impact activities and where you can improve. Think about using time tracking — don’t think of it as time policing.

How to create more “peak” hours during the day.

That may seem like a lot to take in. But, after a week or two, tracking your time should become a habit. But, the main takeaway here is that you also listen to your gut. As I’ve said, you probably have a clue when you’re most productive without having to track your time. But, it’s still worth doing to see what exactly you’re doing and spending your time.

Knowing this, you can then use your “peak” hours more wisely. For me, I’m ready to tackle the day before 8 am. So, I block out from 8 am to 10 am for the most critical task of the day in my calendar. I then take a 30-minute break and get back to work until noon.

Since my energy may start dropping by then — my afternoons are spent on lower energy tasks like meetings. Then I have a snack later in the afternoon, take a break, get revived, and get going again for several hours.

I’ve also been able to create more “peak” hours in the day by taking care of my health — mainly getting enough REM sleep, eating a nutritious diet, and finding ways to relieve stress like meditating and exercising. The reason? All of these can impact your productivity.

Additionally, I also remove the unnecessary items from my calendar. The easiest way to do this is through delegation or dropping them entirely. It’s an effective way to ensure that you aren’t wasting your golden hours on things that aren’t important.
