separate months and then twelve names separated by this character.

means that comma is used to separate the months. Another valid

example ';jan;feb;mar;apr;maj;jun;jul;avg;sep;okt;nov;dec'. So, the

separator should be the first character, before the first month name,

separator, the format is valid. The default value of this property is
