How to calculate a dates difference and show the days of the week

Dear Support, good afternoon,

In the "Checkin Checkout" Widget I want to get the number of days between the 2 dates and the day of the week of each of the dates. How to make ? Thank you.

Thank you for contacting us.

1) To calculate the number of days:

- Use the Date Picker fields.

- Calculate the dates difference using a Form Calculation widget field.

2) To get a day of the week:

- Use the Form Calculation fields.

- Check In Date should receive a date with a dateString function (see this guide).

- You will need to add an 'Update / Calculate Field' condition for each day.

etc.
