ASTranslate is wrong here; it should be 'date_' with a trailing  
underscore, not 'date'.

In situations where application-defined terms conflict with built-in  
terms (i.e. use the same keyword but a different four-char code),  
appscript appends an underscore to the application-defined term to  
prevent any problems.

There was a known inconsistency in how older versions of appscript  
applied these escapes; that has been fixed in the latest appscript and  
ASDictionary releases, but I've not had time to update ASTranslate yet.

Meantime, if in doubt, go by the appscript-style dictionary, which you  
can export as HTML from ASDictionary or browse via appscript's built- 
in help() method (see the appscript manual for details).
