As the saying goes, there are three big problems in computer programming: -- character encodings, -- cache invalidation, -- naming things, -- off-by-one errors.
In Date::Calendar::Ethiopic up to version 0.1.0, there was an off-by-one error when asking for the weekday name. For example, on wednesdays, it would give you "Hamus", which is the translation of "thursday". This is fixed in version 0.1.1, available on zef. No changes for Date::Calendar::Coptic. Thank you for your interest. Jean Forget
