MySQL DATEDIFF Function: Usage Guide

The DATEDIFF function is used to calculate the difference in days between two dates. Its syntax is as follows:

Find the difference in days between two dates, date1 and date2.

Date1 and date2 are two parameters that can be date values, date-time values, or strings that can be parsed as dates.

For example, to calculate the difference in days between January 1, 2022, and February 1, 2022, we can use the following query:

Calculate the difference in days between February 1st, 2022 and January 1st, 2022.

This will return 31, indicating a difference of 31 days between the two dates.

Please note that the DATEDIFF function returns an integer representing the difference in days between two dates. If you need to calculate differences in smaller units of time such as hours or minutes, you can use other functions and operators to achieve that.
