Just a correction, dates in mysql are not strings by any means, they are stored in 3 bytes (date and time or 8 bytes for datetime) and that's nowhere enough for a string, however the representation of the date is a formatted string, so for all intents and purposes any comparison to a date field should be using quotes like mentioned already.
