What does 'DY' return in date formats?

In NetSuite's date formatting, 'DY' returns the all caps abbreviated name of the day. This is useful for displaying dates in a way that preserves space while still providing a clear indication of the day of the week. For example, if you were to format a date as 'DY', and that date fell on a Monday, it would return 'MON'.

Using all capital letters helps to standardize the presentation of the day name, making it easy to read in reports and other date-related outputs. This convention aligns with common practices in programming and data representation where uppercase letters can enhance visibility and recognition. Understanding these date format codes is essential for effectively customizing and utilizing date-related features in NetSuite.
