Disable past dates or display error message?
I am working on a project where there is a datepicker field. Users are not allow to choose past dates(only current and future dates allow). Right now we have two options to design this, which is either to :
- Disable past dates from the datepicker
- Allow user to choose past dates and display error message if user choose past date
Which option should I choose and what are the supporting reasons? Need concrete reasoning to convince other team members.
Any advice, help or article related would be a great help. Thanks in advance!
