Thread:Extension talk:Scribunto/Limits of mw.language:formatDate/reply

The limit is currently 6000 characters total for the format srings in all calls to formatDate (e.g. 6000 calls with 1-character format strings, or 600 with 10-character format strings, 1 with a 6000-character format string).

The limit was copied from ParserFunctions's #time function.
