Date & Time Duration Calculator

Use this calculator to easily calculate how many years, months, weeks, days, hours, minutes, or seconds there are between any given two dates. You can also specify an exact time (hh:mm) for finer time differences.Use this calculator to easily calculate how many years, months, weeks, days, hours, minutes, or seconds there are between any given two dates.

Simply enter the starting date, starting time, end date and time, and press "Calculate". The time duration calculator will display the answer in multiple different time units at once, so you can use the one suitable for your needs.
Date & Time Duration Calculator 
Keep in mind that the calculator always shows the time difference in full years, months, weeks, days, hours, minutes, or seconds between the two points in time, meaning that if there are 120 and a half days the result will show 120 full days. Similarly, if the duration is 3 hours and 59 minutes, the tool will show 3 full hours and 239 full minutes.
Time difference: examplesWe often need to deel with ages, where time differences are of interest. Say you have a friend who is about 1.5 year older than you, but you wish to know exactly how many months, weeks, and days older he is. All you need to do is enter their birth day in the upper field and enter yours in the lower field, or the other way around. Below, the duration calculator will display precisely what the difference is.
Another everyday situation is in transportation, where you need to know how long it took you to get from point A to point B on a bus, train, or in your car. Running the precise start and end time through the calculator will help you plan your next trip to the store or to a business meeting downtown.
Yet another example of how this tool can be useful for you is if you want to start a countdown for an event. Say, your event will start on Feb 20, 2019 at 11:00 and today is Jul 13, 2018, 18:00 (or 6 pm). Then your countdown should start with having 5,321 full hours.
Time difference calculations are common when working with historical events (number of years, months, days between events of interest), in sports (tracking progress over time), transportation, accounting, project management, and everywhere where time management is critical.
Digital, analog, atomic, and Internet timedifference between dates time
A digital clock or watch typically displays the time in digits (through the use of the numbers 0-9). This is as opposed to an analog clock which would show the passing time through moving hands. The digital clock makes it easier and quicker for most people to read the time because you simply need to look at the numbers shown rather than try and figure out where the hands of the clock are. In general, neither digital nor analog clocks are better as it always depends on the quality. The most expensive clocks in the world continue to be analog.
Radio-controlled clocks, on the other hand, get their time from the super-accurate atomic clocks. You might have heard that at a certain time some radios tell you the exact time, and this is where they get it from. To this date there is no more accurate time-keeping device than the atomic clock. A watch or a clock does not tell you the time because it does not know it; it can only show you approximately how much time has passed since you last told it what time it is. Therefore, the watch you have in your pocket is a time-counting rather than a time-keeping device. The Radio-Controlled Clock, on the other hand, is precisely the latter, as it adjusts itself based on the radio signal it receives over and over again by the broadcaster. The time it shows is agreed upon worldwide (known as Coordinated Universal Time, UTC) so this is how you know that it is, in fact, the "right time" [1].
Internet time is a decimal time concept, introduced in 1998 by the Swiss company Swatch. Instead of the traditional hours and minutes, the Swatch Internet Time uses .beats. One .beat is equivalent to 1 min, 26.4 sec; and a mean solar day equals 1000 .beats. There are no time zones in this time concept which makes it easy to have internet appointments with people from around the globe, without having to calculate what time it is supposed to be in their country. Despite the ease in calculation, this mode of time keeping is not very popular and thus not supported in our calculator.
