Date Time Formatting

Alteryx Certified Partner

Hi community,


I have the following date format for the date field 'YYYY-MM-DD' and I would like to somehow calculate only the dates that are 'Saturday'. Is there anyway to do this?

You can create a new field in a Formula tool with the expression...


DateTimeParse([YourDateField], "%A")


...which gives you the day of the week. Then just filter on "Saturday".


You can check out all of the Date Specifiers in Help.

Thanks Rod! I just tried and it says 'Error: Malformed Function Call'


I wrote this: DateTimeParse([Transaction Date],%A)


I checked the format type of the 'Transaction Date' field and it is indeed 'Date'. So I don't know what could be wrong.... Any ideas?

You need quotes around the specifier...

Thank you!


Ok hopefully last question... Alteryx says it cannot convert to weekday because..."  DATETIMEPARSE: Cannot convert "2016-04-20" to a date/time with format "%A":  Weekday is out of range 0..6"

Sorry, @rwood330, this one is totally on me.

It should have been...


DateTimeFormat([YourDate], "%A")


DateTimeFormat goes from Date to String.

DateTimeParse goes from String to Date.


I totally messed you up. ;-(
