The following is a C program to calculate the difference of two dates in years, months and days. Make sure that the start date is earlier than the end date. Try it now. The process of calculating the difference of two dates in terms of years, months and days is quite simple. All we need to do is subtract day, month and year of the start date from the day, month and year of the end date, respectively.

How to compare dates in C/C++
Java examples to calculate the difference between two dates in Java 8. First we will learn to calculate the difference using Jodatime API which was available even before Java 8 release.

In this example, you will learn to calculate the difference between two time periods using a user-defined function. To understand this example, you should have the knowledge of the following C programming topics:. In this program, the user is asked to enter two time periods and these two periods are stored in structure variables startTime and stopTime respectively. Then, the function differenceBetweenTimePeriod calculates the difference between the time periods. The result is displayed from the main function without returning it using call by reference technique.
In this article, we will explore various methods of calculating the difference between two dates in C. We will use DateTime structure for the representation of Date and TimeSpan structure to store the result. We will use the following definition of date, specifying an instant of date using DateTime constructor.
