According to Bede’s De temporum ratione, “Hredmonath is named after their (i.e., pre-Christian Anglo-Saxons’) goddess Hreda, to whom they used to offer a sacrifice during the month” (Karasawa, p. 92).

                   …ϸænne he furðor cymeð

—The Old English Metrical Calendar (Menologium), lines 33b-37a

…then it comes forth among us to town one night later, decorated with hoar-frost and hail-showers, March the fierce, Hlyda the great, comes over the middle-earth. (trans. by K. Karasawa)

Karasawa says that the etymology “is perhaps related to hlud ‘loud'” (p. 92), but there seems to be a lot of speculation about the name’s origin. According to Byrhtferth’s Enchiridion, March is the greatest (swyðost) of months. Karasawa gives reasons for the importance of March (p. 92):

  • The vernal equinox (the 21st) occurs in March, and this date was key for reckoning the date of Easter.
  • March was said to be the month in which God created the world (and a few lines later the poet does refer to the creation of the sun and the moon).
  • Annunciation Day is in March (the 25th).
  • According to Byrhtferth’s Enchiridion, March is when the angels had been created, Christ had suffered but had arisen from death, and God’s spirit had come to mankind.
