I'm making a bot that can take dinner reservations. When it asks for the users reservation time, I'd like the bot to populate my variable $dayoftheweek with the day of the week based on the date the user inputs. How would I be able to do that?

slot

here is my slot "If Found".

value Basically I'd like to know what "value" I could put in to get the day of the week populated.

The easiest would be to use the new system entities (currently in beta). Enable the beta in your skills options. Then, in your dialog node, assign the following:

Check for: @sys-data.day_of_week
save as: mydayofweek

Note that the day names are lower case.

You can use the method reformatDateTime of the expession language to get the day from @sys-date.

For example setting $dayofweek to 

<? @sys-date.reformatDateTime('u') ?>

will set $dayofweek to a value between "1" (Monday) and "7" (Sunday)

or setting $dayofweek to 

<? @sys-date.reformatDateTime('E') ?>

will set $dayofweek to a value between "Mo" and "Su"

The value of @sys-date is stored as a string format "yyyy-MM-dd" e.g. "2016-11-21".

If you want to know what day of the week that date is, you can use the method reformatDateTime:

"<? @sys-date.reformatDateTime('EEEE') ?>"

Here all the posibles values of the method

So your node would look something like this.

Or in JSON format:

{
  "context": {
    "dayoftheweek": "<? @sys-date.reformatDateTime('EEEE') ?>"
  }
}

And here a small test of what would be stored in $dayoftheweek:

Watson: Hello. How can I help you?

User: Day of the week test

Watson: Tell me a date

User: September 13, 2019

Watson: Friday

Here is the JSON Skill for the test.
