Description
Is there a way to ignore case when parsing the month formats 'MMM' or 'MMMM'?
dayjs("2020-NOV-02", "YYYY-MMMM-DD", false); - invalid
dayjs("2020-Nov-02", "YYYY-MMMM-DD", false); - valid
dayjs("2020-nov-02", "YYYY-MMMM-DD", false); - invalid
Contributor guide
Research direction
The issue identifies Day.js's customParseFormat plugin as the entry point; first reproduce the three YYYY-MMMM-DD examples, including the invalid uppercase and lowercase cases. Done means parsing month names with MMM or MMMM accepts differing case while preserving the existing valid behavior, with a regression test for the examples.
