It is evident by inspection that Simaviskambha of any nakşatra (aste

If the zodiacal stretches in muhurtas are converted into zodiacal stretches in days of 30 muhurtas each, we have zodical stretch in days = Zodiacal stretch in muhurtas
. Using this relation, zs in days of any nakșatra may be easily computed. Thus the following table of naksatras and their zodiacal stretches in days may be easily obtained (See table No. 3).
TABLE No. 3 Nakşatras and their zodiacal stretches (=ZS) in days
Total number of nakşatras (Asterisms)

In the light of the foregoing discussion this shows that Simāviskambhas of nakşatras (asterisms) represent their zodiacal stretches in days expressed as fractions having the same denominator probably for a better comparison. Thus the zodiacal circumference was graduated in days of a nakşatra month i.e.
54900 days. The correspondence between days of nakşatras and the mo30 x 67 dern degrees of arc works out as follows :
54900 30 x 67 days (time degrees)
=

30 x 67 days
