Condition to check the day of the week

[E1cid]

@jbudd showed you how to get the day of the week using getDate() (value 0-6, sun to sat). here
You can use that outptut in a msg property, then use a switch node to direct, where rules would be -
Property would be value you save the 0-6 in
Rule 1 == (number) 0
Rule 2 == (number) 1
etc.
