To enter a date and time together, use a single space between time and date like this: 10:00. You can simply the problem of calculating elapsed time drastically using values that contain both date and time, sometimes called "datetimes". If you need this, see the date + time option below.įor more on modulo, here's a good link on Khan Academy. Note: neither formula above will handle durations greater than 24 hours. Because this formula will handle times in the same day and times that span midnight, we don't need a conditional IF statement.
#TIME TO TIME CALC MOD#
This formula takes care of the negative time by using the MOD function to "flip" negative values to the required positive value. By using the MOD function with a divisor of 1, we can create a formula to handle both situations: =MOD(end-start,1) The MOD function provides an elegant way to simply the formula above. But when the times across a day boundary the second formula is used. When both times are in the same day, end is greater than start time, the simple formula is used. This formula won't work for times that occur the same day, so we need to use IF function like this: =IF(end>start, end-start, 1-start+end) To correct this problem, you can use this formula for times that cross a day boundary: =1-start+endīy subtracting the start time from 1, you get the amount of time in the first day, which you can simply add to the amount of time in the 2nd day, which is the same as the end time. For example, if the start time is 10:00 PM one day, and the end time is 5:00 AM the next day, the end time is actually less than the start time and the formula above will return a negative value, and Excel will display a string of hash characters (#). This means times and hours are fractional values of 1, as shown in the table below: HoursĬalculating elapsed time is more tricky if the times cross a day boundary (midnight). In Excel, one day equals 1, which represents 24 hours.
However, when times cross a day boundary (midnight), things can get tricky. To see the result in hours and minutes, apply a time number format like this: h:mm
For example, with start time of 9:00 AM and an end time of 5:00 PM, you can simply use this formula: =end-start When start time and end time occur in the same day, calculating duration in hours is straightforward. This article provides several formula solutions, depending on the situation. This is because times that cross midnight often have a start time that is later than the end time (i.e. If you are very strict, or you have the requirement about worktime management (voluntary or be required), or you like to record the work time for some important works, it may be useful.The complexity of calculating the number of hours between two times stems from times that cross midnight. Of course, some useful options are built-in: refreshing frequency, precision of the numbers of years, months, weeks, days, hours, minutes and seconds, font name and size of the works listing, foreground colors of different work status.Įasy Work Time Calculator is a simple yet useful worktime manager with, also, it has a nice and friendly user interface and some useful settings to improve the user experience. With this program, you can Start, Rename, Delete, Pause, Restart and Stop your works, it provides you with the convenient filters to see the works as you need.Īlso, copying the value of any field, data backup/restoring features are provided. The numbers of date time elements are refreshed automatically, and you can set the refreshing frequency.
It can calculate/count time consumption of your works by seconds, minutes, hours, days, weeks, months and years. Easy Work Time Calculator is an easy to use worktime calculator.
