No, only one date can be entered per date question. To capture a date range, you will need two date questions. The Appointment field can also be used to capture a range of dates. To do this with an Appointment field:
Add an Appointment field to your form.
Click the "Configure" cog to the right of the field.
(Optional) Connect one or more calendars.
Select Days from the "Appointment mode" dropdown.
Click the "Event Details" tab, add any details you want to include, and click "YES" under "Is length of time chosen by the submitter?"
Adjust the minimum and maximum length of the range you would like submitters to choose. You can also select None for no minimum or maximum.
Click the "Availability" tab and choose your general availability. Users cannot select a range that includes days you are not available, including availability on any connected calendars. We recommend you toggle on all days and avoid adding Blockout dates if you want users to select longer date ranges.
(Optional) Adjust "Number of days in advance an appointment can be made" and, "Minimum number of days notice."
