Merits ::...

*This program gives the academic calendar for any years calendar

* Includes leap year

*Very helpful in the field of astrology

*Alignment is similar to that u see in your normal wall calendar

Look out ::...

This program can be run in any C compilers... Important thing is that the output will only be displayed in a notepad file outside the compiler... This is because while displaying the entire year's calendar only a last few months are visible in DOS PROMPT after execution.... So in case of notepad file entire years calendar can be displayed....

Your comments are always welcomed....

U may know ur date of birth but ur day of birth !!!

DATE ----------->>> DAY

Intro ::..

This program is used to find the day of a any given date... This may be your birthday or the day u met your first spouse or anything else.... This program is created with the last program as a base...

Merits ::..

* This program too has no exceptional cases...U can know even the day when Buddha was born if u know the date....

Look out ::...

This program can be run on any normal C compilers...

Want to know your age in days....

DATE - DATE ===== ?????

Intro ::..

This program is built to find the difference between of days between the two given dates... The C language is used for its construction... This is the first program that i have tried out with a great grit... I thank my teacher since she is behind its thought...

Merits ::...

* I have tried out for almost all possible inputs and there are no exceptional cases...

Look out ::..

By copying this code and placing it in your any of the C compilers you can exectute the program...
