Get days of week – Virtuoso

The Date/getDaysOfWeek extension generates an array of formatted dates starting from the current date.

This is useful when a journey needs a list of upcoming dates, such as the next seven days, in a specific display format for date validation or test data generation.

Parameters:

daysrequired required, a string or number representing how many dates should be generated. The script converts this value using parseInt(daysrequired);
dateFormat required, a string containing the Moment.js date format used to format each returned date;

Note: The first returned value is based on the current date. Each next value adds one calendar day using Moment.js add(i, 'd').

NLP usage

Use the extension in a journey by calling Date/getDaysOfWeek with the execute command. Pass each value to the matching extension input using as inputName.

Note: The dateFormat value must be compatible with Moment.js formatting tokens.

execute "Date/getDaysOfWeek" using "7" as daysrequired using "ddd DD MMM" as dateFormat returning $daysInAWeek

execute "Date/getDaysOfWeek" using "5" as daysrequired using "YYYY-MM-DD" as dateFormat returning $weekDates

You can also pass stored variables into the extension inputs.

execute "Date/getDaysOfWeek" using "$numberOfDays" as daysrequired using "$format" as dateFormat returning $daysInAWeek

store value "7" in $numberOfDays
store value "ddd DD MMM" in $format
execute "Date/getDaysOfWeek" using "$numberOfDays" as daysrequired using "$format" as dateFormat returning $daysInAWeek

Example output for seven dates formatted as ddd DD MMM:

[
  "Mon 25 May",
  "Tue 26 May",
  "Wed 27 May",
  "Thu 28 May",
  "Fri 29 May",
  "Sat 30 May",
  "Sun 31 May"
]

This extension requires the following resources:

https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.29.2/moment.min.js

The extension should be configured as:

Run asynchronously: No
Scope: Global

Limitation: The script depends on Moment.js being loaded from the configured resource. It uses the current browser/runtime date and timezone, so results may vary depending on where the journey is executed. The daysrequired input is parsed with parseInt, so non-numeric or partially numeric values may produce unexpected output, and the script does not add validation for invalid date formats.
