# Duration field

> Duration input for Airtable Duration fields.

## What this does

The duration field maps to Airtable's Duration field type. It presents a structured input for entering a time duration (hours, minutes, seconds).

## Settings reference

The duration field has no field-specific settings beyond the universal ones.

**Universal settings that apply:** Label, description, required, read-only, conditional visibility, conditional read-only, must be unique, custom validation rules.

## How the input works

The duration field accepts a time duration in the format configured in your Airtable field (hours:minutes or hours:minutes:seconds). The format is determined by your Airtable field settings, not by Filla.

## Common use cases

* Time tracking forms (how long did you spend on this task?)
* Video or media duration entry
* Session logging forms (how long was the meeting?)

## Common questions

<AccordionGroup>
  <Accordion title="What format does the duration field use?">
    The format matches your Airtable field configuration. Airtable supports `h:mm`, `h:mm:ss`, and `h:mm:ss.s`. Set the format in Airtable; Filla reads and displays it accordingly.
  </Accordion>

  <Accordion title="Can I validate that a duration is above a certain threshold?">
    Use custom validation rules to add constraints, for example "duration must be greater than 0:30" for a minimum 30-minute session.
