How the Date field works
Updated 2 weeks ago
The Date block uses your respondent's browser-native date picker, so the display format follows their device's locale, not a setting in Youform. Youform stores and exports the answer in YYYY-MM-DD, and that same format is required when you auto-fill the field from a URL parameter.
How the date picker displays
The Date block renders the browser's native date control, so the layout a respondent sees (for example, month-day-year versus day-month-year) is determined by their browser and operating system locale. Youform does not apply a custom display format, and there is no setting to change it.
No date range, minimum or maximum date, or past/future restriction is applied to the field.
Auto-fill format for URL parameters
When you enable Auto fill via URL parameter on the Date block, the value you append to the form URL must use YYYY-MM-DD. For example, if you set the parameter to birthdate, appending ?birthdate=1995-12-25 to the form page URL fills the field with that date.
For the general setup of this feature, see Auto-filling via URL parameters in Youform.
How date answers are stored and exported
Youform stores the date answer as the raw YYYY-MM-DD value. The CSV export writes that same value in the question's column, and integrations such as Google Sheets, Slack, and webhooks receive the stored value unchanged.
In Google Sheets, Youform passes the value through without formatting it, so how the cell renders depends on Google Sheets' own interpretation of the value.
