Hi, I have this date coming from a date picker. 01/30/2023
how can I know what day it is?
Ex.
01/30/2023 - MONDAY
Hi there, @guybean… one way you can go is to create an option set that has the days of the week and an attribute for each option’s day number (each day has a corresponding number, with Sunday=0, Monday=1, Tuesday=2, etc). Then, extract the day from the date picker’s date and get the option from the option set where the day number attribute matches the date’s day, and you’ll be good to go.
Hope this helps.
Best…
Mike
Edit: If it helps, here are a couple of screenshots. Here is what the option set would look like, and you would modify the attribute of each option and enter the associated day number.
Here is the expression in a text element that would get the day of the week associated with a date/time picker’s value.
You can use the operator :Extract (Day) on a date to get the day of the week.
The days are represented by a number, from 0-6, with 0 being Sunday and 6 being Saturday.
The simplest way would then be to create an Option set of Days, with the corresponding Day number, then use that do display the name of the day.
