To sum times you usually use Excel built-in function SUM. If you have three cells A1, A2 and A3 formatted as time (hh:mm), and you have :
A1 = 02:30
A2 = 10:15
A3 has the formula: =SUM(A1:A2)
then A3 will have the correct values of 12:45.
However if your total times are greater than 24 hours then things get [...]
If you have a time in a decimal format, i.e. an integer and a fraction, e.g. 2.5 hours (2 and a half hours) and you want to convert to a standard time format 02:30 (2 hours and 30 minutes), then you can use a formula based on the TIME function with the following syntax:
TIME(hours,minutes,seconds)
Example:
We have [...]
If you have a standard time, current time for example, and you want to add to it hours, minutes or seconds to get to a new time, then what you need to do is to convert the hours or minutes to a standard time format using the TIME function. After that you can add [...]
If you have a number of time values you want to add together, e.g. total hours worked by an employee in the week, then you can list those hours in a standard time format (hh:mm or hh:mm:ss) and sum them together.
Example 1 : total hours less than 24.
Cells B1, B2, B3 and B4 contains the [...]

The way you calculate the difference between two times depends on the way you want to present your results:
1. Present the result in standard time format (hh:mm:ss).
Simply subtract the two times from each other and format the result cell as time.
Examples:
A1 = 9:15:00
B1 = 14:07:20
Difference = B1-A1 = 4:52:20 (4 hours, 52 minutes and 20 [...]
To calculate the difference or the number of days between two dates, you simply subtract one date from the other.
Example (using format:dd/mm/yyyy):
Suppose you have the date 25/11/2007 in cell A1 and the date 15/01/2008 in cell B1 (both cells formatted as date). To calculate the difference between these two dates you use the following formula:
=B1 [...]
To extract day, month or year from a date, you use the corresponding Excel built in function for each one of these date parts.
Day: Day(mydate).
Month: Month(mydate).
Year: Year(mydate).
Examples:
Suppose you have in cell A1 (formatted as date), the date:15/11/2009 (ddmmyyyy), Then:
Day(A1) will result in 15
Month(A1) will result in 11
Year(A1) will result in 2009
Applies [...]
This step-by-step article shows you how to calculate the number of months between any two dates.
To calculate the number of months between any two dates, use one of the following methods. Note that both methods use the following information:
• EDate = Earlier Date
• LDate = Later Date
NOTE: If you type LDate or EDate directly into this formula [...]
If you want to get the current date and time in a cell then you can do one of the following:
1. To get the current date only use the TODAY() function.
Syntax
=TODAY()
2. To get the current date and time use the NOW() function.
Syntax
=NOW()
3. To get the current time only use the NOW() function, and then format [...]
