It overlaps September and October of the Gregorian calendar and is the month preceding Diwali, the festival of lights. The month is here named Ashshin, Bangla lipi আশ্বিন). In lunar religious calendars, Ashvin begins on the new moon after the autumn equinox.
Asawin is the Thai variant of Ashvin and stands for warrior. The term is often translated into English as "knight".
The English name Ashwin, or in Anglo-Saxon, Æscwine, translates literally as "ash-tree friend", but can mean a number of things, including "strong/manly friend", or "friendly man." Anglo-Saxon compound names were often poetic rather than literal. For example, "Beowulf" could mean "bee-wolf", "bee-hunter", or simply "bear" (one who hunts for bees). Attested in the Poetic Edda, the first man was made from the log of an Ash-tree and was named Ash.
Ashvin, Ashvini, Ashwin, Ashwini, Aswin and Asvin are common names originating in Sanskrit. The distinctly formed Anglo-Saxon surname Ashwin and Aescwine are less common. Ashwin is known as aipasi (ஐப்பசி ) in Tamil and begins when the sun enters Libra in October.
