This gets really confusing if you’re from Limburg. In Limburgish, “daan” (the cognate to Dutch “dan”) only exists as the time indicator. With comparisons the correct Limburgish is to use “es” for differences (e.g. “Jan is groeter es Maria”, “John is bigger than Mary”), and “wie” for equivalents (e.g “Jan is eve aajd wie Maria”, “John is as old as Mary”). Now “es” is cognate to Dutch “als”, but using it in Dutch as in Limburgish is wrong. So yeah this gets confusing.
