Should I allow users to input the MMDDYY or MMDDYYYY format for a date?
That is, should any date validation logic not trigger a validation error if the user just wants to put in the numbers without any separation symbols (.
, -
or /
)?
Answer
The usual caveat of "it depends" applies -- if the users are typing in dates which they are reading off from somewhere else, and that reference material is formatted as MMDDYY or MMDDYYYY then, yes, let them simply transcribe it.
Also, if the users are data entry process workers (eg. in a call centre) and not casual website visitors, then let them perform data entry in a keystroke efficient manner.
