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.
• OL_MASK 🔒
• ORDINAL_MASK 🔒
• WEEKDAY_FLAGS_MASK 🔒
• YEAR_DELTAS 🔒
