Yesterday, I have released to CPAN6 the version 0.0.1 of Date::Calendar::CopticEthiopic which implements the Coptic calendar and the Ethiopic calendar and the version 0.0.2 of Date::Calendar::Strftime.
New features for strftime : -- Week-related attributes, which produces a "ISO date" such as "2019-W49-4". -- It it more or less possible to use strftime on objects from the core class Date: OK for numeric attributes, but no alphabetic names nor abbreviations. And already a bug: Through a late-minute update, a wrong URL was stored in META6.json. Therefore, the test suite fails. Installation is possible with "--force-test". Fixed in Github, but I will wait a few days to release a new CPAN6 version, in case other problems are found and fixed. Thank you for your attention, Jean Forget JFORGET at cpan dot org
