This module implements the {{Roman Date}} template. For behavioural documentation, please see the template page.
- This module supports dates formatted in the form YYYY-MM-DD or MM-DD
- This is a new module and may be subject to bugs, to report bugs please use the discord
- This module also supports leap years
Known Bugs
- Doesn't check for dates that are past the maximum number of days in a month
- Doesn't check for dates below 1 and thus may fail
