Exeligmos
  چرخگرد   
Carxgard

Fr.: exeligmos   

A period of three → Saros cycles, that is 54 years and 34 days (19,755.96 days) that can be used to predict successive → eclipses with similar properties and location. As the Saros cycle is a period of about 6.585 1/3 days, the 1/3 day means that after 223 → lunar months all eclipses are shifted by about 8 hours (or by about 120° in longitude). Exeligmos contains a whole number of → synodic months (669), it also contains a whole number of → anomalistic months (717), and → draconistic months (726). So, after one exeligmos, the Moon will again be near the same node of its orbit. Thus we have a very good chance of finding an eclipse. Moreover, since an exeligmos also contains a whole number of days, the eclipse will even occur at about the same time of day as before. But because the Moon moves 32° in mean longitude, over and above complete cycles, during an exeligmos, the second eclipse will occur approximately one zodiac sign farther east than did the first one (James Evans & J. Lennart Berggren, Geminos's Introduction to the Phenomena, A Translation and Study of Hellenistic Survey of Astronomy, 2006, Princeton Univ. Press).

Exeligmos, Gk. "turn of the wheel."

Carxgard "turn of the wheel," from carx, → wheel, + gard "turn," → revolve.

2b) To put through exercises, or forms of practice or exertion, designed to train, develop, condition, or the like (Dictionary.com).

M.E., from M.Fr. exercice, from L. exercitium "training, exercise" (of soldiers, horsemen, etc.); from → ex- "off" + arcere "keep away, prevent, enclose."
