Why isn't this a date?

[Mikey]

If I
put "07/01/77" into thisCrap
put thisCrap is a date

I get false

put "07/01/1977" into thisCrap
put thisCrap is a date

I get false

Indeed there are no date operators that seem to work on thisCrap.
This is at least a little annoying as it means I have to manually
massage all the dates I extract from a file I'm working on.

Yes, I chose the name so we can have a good laugh about how there are
lot of things that don't work on thisCrap.
