Date/time asks for a date, a time or both. Participants type the date or pick it from a calendar, so the answer always has the same format. Use it for birthdays, start dates, appointments or the date of an event.
Participants click the calendar button next to the field to pick a date. The expected format is shown below the field, for example Format: mm-dd-yyyy.
Click the purple + in the top bar. The question type picker opens.
Under Dates & data, click Date/time. The question appears at the end of the current question group.
Click Your question here and type your question.
Select the question to open its settings on the right. The main settings are on the Simple tab.
The answer is stored as a date, and as date and time when the format includes a time. In the export it is one column per question.
Set Date/time format in the question settings, or change the date format of the whole survey under Presentation > Presentation.
Set Minimum date and Maximum date. The calendar then offers only the days in between.
