The starting point for the nakshatras is the point on the ecliptic directly opposite to the star Spica called Chitrā in Sanskrit (other slightly different definitions exist). It is called Meshādi or the "start of Aries". The ecliptic is divided into each of the nakshatras eastwards starting from this point. The number of nakshatras reflects the number of days in a sidereal month (modern value: 27.32 days), the width of a nakshatra traversed by the moon in about one day. Each nakshatra is further subdivided into four quarters (or padas). These play a role in popular Hindu astrology, where each pada is associated with a syllable, conventionally chosen as the first syllable of the given name of a child born when the moon was in the corresponding pada.
