Overview
Filla supports two date field types:| Airtable field type | Form input | Best for |
|---|---|---|
| Date | Date picker calendar | Birthdays, deadlines, event dates |
| Date Time | Date-time picker with time component | Appointments, meeting times, scheduled events |
Settings reference
| Setting | Description |
|---|---|
| Auto-fill today’s date | Automatically fills the field with today’s date when the form loads. Respondents can change it unless the field is also read-only. |
| Block past dates | Prevents selection of any date before today. Use this for future-only scheduling. |
| Block future dates | Prevents selection of any date after today. Use this for past event recording or birth dates. |
| Minimum date | The earliest date a respondent can select. Uses an absolute date picker. |
| Maximum date | The latest date a respondent can select. Uses an absolute date picker. |
Common date configurations
Appointment scheduling: Enable Block past dates so respondents can only select upcoming dates. Optionally combine with a Maximum date to limit bookings to the next 30 or 60 days. Recording past events: Enable Block future dates so respondents can only select a date that has already passed. Date of birth: Enable Block future dates to prevent future dates. You might also set a Minimum date far in the past to prevent obviously invalid birth years. Fixed event registration period: Set both a Minimum date and Maximum date to constrain the selectable range to specific dates.Auto-fill today’s date
When enabled, the field pre-fills with today’s date the moment the form loads — no respondent action, no URL parameters, no default-value setup needed. This is the simplest way to prefill a date field with the current date. Use it for fields where today is almost always the right answer:- “Date of inspection”, “Report date”, “Submitted on”
- “Application date”, “Date completed”
- Any timestamp the respondent shouldn’t have to think about
Editable vs read-only
Default (editable): The field pre-fills with today’s date. The respondent can change it if they need to backdate or schedule. Read-only + Auto-fill today’s date: The field stamps today’s date automatically and the respondent cannot edit it. This is the canonical pattern for “auto-stamp the submission date” fields where you want a guaranteed accurate timestamp.Comparison with other prefill methods
| Method | Best for | Where |
|---|---|---|
| Auto-fill today’s date | Stamping the current date | Date / Date Time field settings → Date options |
| URL parameter | Passing a specific date from your CRM / app | ?prefill_FieldName=2026-04-25 in the form URL |
Common questions
How does the date format display to respondents?
How does the date format display to respondents?
The date format follows your Airtable field’s configured format. If you set the field to show dates as “January 1, 2026” in Airtable, that is how it appears in the picker.
Can I restrict to only certain days of the week?
Can I restrict to only certain days of the week?
Not currently. You can restrict by date range (min/max) and direction (past/future), but not by day of the week.
Does the time component respect time zones?
Does the time component respect time zones?
The time is stored in the respondent’s local time. Airtable stores date-time values in UTC. Check your Airtable field’s time zone settings to control how the time is interpreted.
