The following formula shows how to convert a date value to the day of the week.
To do this we need to use:
- DayOfWeek – this takes a date and converts it to a number, representing the day of the week (e.g. 3)
- WeekdayName – this converts a given number to the weekday name (e.g. Tuesday)
Note: both these functions use Sunday as the first day of the week – however, as we’re using them together this is of no significance.
To use, create a formula field in your Crystal Report – recreate the formula using the code below as an example and add to your report.
WeekdayName( DayOfWeek ( {Table.Date} ) )
