How to calculate the number of days in this month?

Step 1: Add a short answer question with number response validation in Google Forms.
Step 2: Click on the Addon icon > Select Formfacade > Select Customize this form > Click on the Proceed button.
In the Formfacade customize interface, click on the ⚙️icon next to the short answer question for number of days in this month.
Step 3: Field settings screen will be displayed. Select the "Answer" tab and write the formula to calculate the days in this month.

Use DATE function to calculate the days in this month

The first step is to calculate the last date of this month. We can pass the year, month and day to the date function.

TODAY().year() will return the current year
TODAY().month() will return the current month
DATE(TODAY().year(), TODAY().month()+1, 1) will return the first day of next month.

We can then use the SUBTRACT function to find the last day of this month.
DATE(TODAY().year(), TODAY().month()+1, 1).subtract(1,"days")

There is another way to calculate the last day of this month without using the SUBTRACT function.
DATE(TODAY().year(), TODAY().month()+1, 0) will return the last day of this month.

We can use the getDate() or date() function to find the day of the month for a specified date.
DATE(TODAY().year(), TODAY().month()+1, 0).date() will return the last day of the month.

Step 4: Write the above formula in the Calculate option as shown below.

days_in_this_month - TODAY().date()
