Custom date validations

Overview

Acrobat Sign provides several standard formats for date validation, but many businesses have a need for the date to be in a very specific format. To accommodate all use cases, Acrobat Sign allows users to define their own custom date format using characters as variables (representing how the day/month/year etc. are presented) and separators to clearly divide the date values.

Availability:

Date validations are available for individual, team, and enterprise license plans.

How it's used

Users that author fields onto documents can use a Text field to accept a date value and then define the acceptable format of the date using a date validation.

In cases where one of the preformatted options doesn't fill the need, a Custom validation can be created.

Text field with the Dave options exposed

The form of the validation is defined using alphabetic characters as format tokens that represent values for the following:

  • Day - Either in a shortened version or fully spelled out.
  • Month - Either in a shortened version or fully spelled out.
  • Year - In two or four digits.
  • Hour - Either military or standard time.
  • Minute - Either retaining or trimming a leading zero.
  • Second - Either in a shortened version or fully spelled out.
  • AM/PM - Either the first character or both.

Things to know

When designing the validation format in the field properties, an example of the format is dynamically exposed under the field to provide an example of what the required input will be.

Recipients that enter a date in a format other than the designed validation form will trigger an error message that provides the exact form required.
