Can I use Butler to add the weekday name to a custom field

[Lyndsey Fletcher]

Can someone tell me if it is possible to use Butler to work out the day of the week from a due date and return that value to a custom field? If it is possible - can anyone help with me how to do it? 
Manu Thanks

@Lyndsey Fletcher - hi Lyndsey! This is possible - make a new Automation rule like so:

when a due date is set on a card by me, set custom field "Due on Day of Week" to "{cardduedateweekdayname}"

Of course, your custom field may have a different name than what I used above ("Due on Day of Week").

For more variables you can use, check out the Butler variables Help page: https://help.trello.com/article/1157-variables#time-and-date-variables

Happy to help - it's a fun way to start a Saturday. 🙂

@Lyndsey Fletcher - p.s. Also consider making a rule to cleanup the field if someone removes the Due Date:

when a due date is removed from a card by me, clear custom field "Due on Day of Week"

Thank you! I will be back for more  advice with the next step of this...  this is to fit a very specific planning method I use and use Trello for. Right now in the UK - it’s dinner time and I am hungry!
