length of tropical years and calendar years in mean solar days

Summary[edit]

Description
Deutsch: Basierend auf: File:TropicalAndGregorianYear MeanSolarDays.png, Autor: user:Sch

Länge des Jahres in mittleren Sonnentagen (also unter Berücksichtigung der langsamer werdenden Erdrotation) für:

  • tropisches Jahr alter Definition (hellgrün), also von Frühlingsäquinoktium zu Frühlingsäquinoktium
  • tropisches Jahr alter Definition (schwarz), also Zeit, welche die mittlere Sonne für 360° auf der Ekliptik braucht
  • mittleres Jahr nach dem gregorianischen Kalender (grau gestrichelt), 365,2425 Sonnentage
  • mittleres Jahr nach dem neo-julianischen Kalender, (dunkelgrün gestrichelt), 365,24222… Sonnentage
Geeignet zum Vergleich der Genauigkeit beider Kalender, bezogen auf Intention (Osterdatum bzw. Frühlingspunkt)
English: Length of year in mean solar days (allowing for the slowing-down of the Earth's rotation):
  • tropical year, old definition (green), i.e. from spring equinox to spring equinox
  • tropical year, new definition (black), i.e. time needed by the mean sun for 360° on the ecliptic
  • Gregorian calendar year (dashed grey), 365.2425 solar days
  • Revised Julian calendar year (dashed dark green), 365.24222… solar days
