Can you specify two formats in OpenAPI?

Question

I need that a field on my JSON scheme to be either date or datetime. It can have any of those formats. Using the format property, is it possible to use both formats?

I myself asked the same question. However is it even good to use such a pattern? Wouldn't it make more sense to always transmit a datetime and an allday boolean flag instead? I am not sure, its 50:50, maybe you can give me a better opinion on that. — NicoHood

In OpenAPI 3.x, you can use anyOf:

type: string
anyOf:
  - format: date
  - format: date-time

OpenAPI 2.0 (swagger: '2.0') does not support anyOf, but as a workaround you can provide a custom regex pattern instead of the format.
