The Julian Calendar
The Julian calendar is a solar calendar that was used commonly historically, with twelve months.
This type can be used with Date
or DateTime
to represent dates in this calendar.
§Era codes
This calendar supports two era codes: "bce"
, and "ce"
, corresponding to the BCE/BC and CE/AD eras
§Month codes
This calendar supports 12 solar month codes ("M01" - "M12"
)
