Jāra or Jēra "harvest, (good) year" is the reconstructed Proto-Germanic name of the j-rune ᛃ. In the Anglo-Saxon Futhorc, it is continued as ᛄ Gēr and ᛡ Ior, the latter being a bind rune of Gyfu and Is.
Its name is continued as ᛅ Ár in the Younger Futhark. The corresponding Gothic letter is 𐌾 j, named jer.
