Hi Joe,

You could just handle the error.

['1/22/2016' asDate class = Date ] on: Error do: [:ex | ^false] 
returns true

['15/22/2016' asDate class = Date ] on: Error do: [:ex | ^false] 
returns false

Or even 

[myDate := '1/22/2016' asDate] on: Error do: [:ex | ^nil].

Then you can just check if myDate isNil.

All the best,
