DATE ARITHMETIC
DATE ARITHMETIC
Manual date calculations can be tricky because you have to keep track of the
number of days in a month.
 In spreadsheets, date calculations become very simple.
Here you can add a number to a date and arrive at a new date, find the difference
between two dates and use a wide variety of function and formats to get what you
want.
For example, enter a date 03/04/05 in a cell, say A2. Remember that while entering
dates the month always comes first.
Suppose you want to calculate the date 79 days after this date.
To do so, enter the formula, = A2 + 79, in another cell, say A4. The date 05/22/05
appears in the cell.
Now, suppose you want to calculate the difference between two dates, 05/10/05 and
12/8/70. To do so, enter the two dates in two different cells.
In a third cell enter the formula = first cell – second cell. The result will be
displayed as 12572.
THANK YOU..!!
