How does the function LAST_DAY help in date calculations?

The function LAST_DAY is designed specifically to identify the last day of the month for a given date. When you provide a specific date as input, LAST_DAY will return the date that corresponds to the final day of that particular month, regardless of the year or other conditions. This is especially useful in various financial calculations, reporting, or scheduling where it is essential to know the end of the month.

For instance, if you input a date like March 15, 2023, the LAST_DAY function would return March 31, 2023. This functionality simplifies date management in software environments like NetSuite, enabling users to automate and streamline tasks related to month-end processing without needing additional logic to compute the last day of any given month.
