Counting Time Calculator

Can you count time without a clock? Test using the counting timer and see how precisely you can keep track of time!


Enter between 2 and 10 seconds

Select how many seconds to count without a clock

Yes: Slow Motion Effect at Start of Counting; No: No Effect

How to Use Counting Time Calculator

  1. Countdown to Start Test - Select how long you want to prepare to count heart beats. This gives you time to locate your pulse, so that when the BPM counter starts, you're good to go.

  2. Counting Time - This is the number of seconds you will try to count to without a clock. You can count your pulse for 10 seconds up to 60 seconds. Longer intervals tend to be more intervals, so it's recommended you start low and work your way up.

  3. Slow Motion Effect - If Yes is specified, when the screen where you'll count displays, per below, a slow moving fade in/out color bar displays for the first part of your count. It's designed to provide a sense that you've started your counting time on an otherwise static screen. If you find it's distracting to your time counting, set this field to No.

  4. Click or Tap Go - Once you've setup the above, click/tap GO.

    Start counting to your destination Counting Time as soon as the screen turns green and displays the Done button.

    When you think you've counted to your destination number, click or tap Done. Your counting accuracy displays.

Do Humans Have Internal Clocks?

It is said that not only do people have internal clocks, also referred to as biological clocks, but that every single cell in one's body has a clock designed to synchronize with the surrounding environment.

Circadian Rhythms are changes humans, as well as other animals and orgnaisms, experience over a 24 hour period, which are physical, mental and behavioral and regulate sleep patterns, appetite, digestion, hormones and more.

Circadian Rhythms are primarily controlled by light and darkness; Environmental changes, such as travelling to a different time zone, can alter one's circadian rhythm. It's why, for examples, time travel can cause jet lag until the body re-adjusts to the time zone change.

There are many people who do not need an alarm clock, and wake up, like clock-work, at the same time every day. For some, however, the switch to or from daylight savings time throws off their internal clock, until their body does an internal reset.

Why count like a clock?

At a time when time surrounds us, via the ubiquitous presence of cell phones, wearables, and time pieces on so many other devices, what's the point of counting time? Some reasons include:

  • It's interesting to see if you can keep track of time like a clock.

  • It's challenging, but doable, to train to be an accurate time keeper.

  • It's rewarding to go up against time and conquer it!

  • Certain situations call for counting time where it's easier to do so in your head than using a clock or stopwatch. (See BPPV example below)

If dealing with Benign Paroxysmal Positional Vertigo (BPPV), one effective solution is a series of physical maneuvers, which need to be held for 30 seconds while looking in a specific direction. With a stopwatch, one would break that hold by constantly having to look at a clock. By being able to closely count to 30, one can completely focus on the exercise.
