Constants

LEAP_YEAR_MASK 🔒

MAX_DATEDeprecated

The maximum possible NaiveDate (December 31, 262143 CE).

MAX_OL 🔒

MAX_YEAR 🔒

MAX_YEAR is one year less than the type is capable of representing. Internally we may sometimes use the headroom, notably to handle cases where the offset of a DateTime constructed with NaiveDate::MAX pushes it beyond the valid, representable range.

MIN_DATEDeprecated

The minimum possible NaiveDate (January 1, 262145 BCE).

MIN_YEAR 🔒

MIN_YEAR is one year more than the type is capable of representing. Internally we may sometimes use the headroom, notably to handle cases where the offset of a DateTime constructed with NaiveDate::MIN pushes it beyond the valid, representable range.
