Answers
Answer:
Excel stores dates and time as serial numbers. When you format the serial number as a date or time, or date and time as in the example below, it displays it in a date/time format but underlying is still a serial number.
The serial number is made up of two parts.
Serial Number
The digits before the decimal are the date and the digits after the decimal are the time.
Excel Time Serial Numbers
Dates in Excel
Dates in Excel start on 1st January 1900. Therefore the serial number for 1/1/1900 is 1.
The serial number for 1/1/2012 is 40909 because it is the forty thousand, nine hundred and ninth day since 31/12/1899*.
Excel Date Serial NumbersNote: in Australia our dates are displayed as dd/mm/yyyy.
*Actually 1/1/2012 is only the 40908 day but Excel includes the date 29th Feb 1900 even though 1900 was not a leap year. This inclusion was intentional to provide compatibility with Lotus 1-2-3 which contained the bug and had the market share when Excel was released!
Time in Excel
Time serial numbers represent a fraction of a 24 hour day.
Excel Convert Time to decimal
Convert Time to Decimals
Often we need to convert time to a decimal so that we can calculate hours x rate for the purpose of payroll or billing.
It’s easy. Remember, the serial number is a fraction of a day so you simply multiply it by 24.
Excel Convert Time to decimal
Note: you don’t need to enter a date and time. If you enter time only, the date part of the serial number is 0.
OK, now you know the rules let’s look at some examples or working with time.
Shift Work Timesheets and Overtime
Calculating the difference between two times on the same date is as simple as subtracting the start time from the finish time, but it’s not so easy if your start and finish times are on different dates, as in the case of shift workers.
Notice the finish time below for Monday is actually 7AM on Tuesday.
