How does Hive calculate the number of days between dates?

In Hive, you can use the datediff function to calculate the number of days between two dates.

For example, if we have a table with date fields date1 and date2, and we want to calculate the number of days between the two dates, we can use the following Hive query statement:

SELECT datediff(date2, date1) AS days_interval
FROM table_name;

This will return a result set containing the number of days between the dates.
