Have you ever thought about how many days have you been staying on this world since you were born? I have found a quick way to calculate it using Microsoft Excel.

As the example above, if you were born on 8/8/2008, You are 74 days old today, and on Chrismas day of the year 2035, you will be 10000 days old.

Here is the trick:-
0.  Open a new excel files.
1. Enter your birth date (in cell B1).
2. Enter today date (in cell B2).
3. The answer for the number of days until today since you were born is =B2-B1.
4. The answer for the date of your 10000th day birthday is =B1+10000.
5. [for B3] After doing the plus and minus operation on date, excel may display number in date format because the answer is not formatted properly. Therefore, the next step would be formatting the cell B3. Change the cell format from date to number.

It is very simple and easy if you have the basic skill on Microsoft Excel.

I have a feeling when I look at my age in the unit of days. I have only been living in this world for 10700+ days. If I have a long life and can reach 100 years old, it would be only 36500+ days. I feel that life is short.

I should not waste anymore time, and should work harder to pursuit my happyness.
