330 yojanas of the Lavanasamudra. Thus in both Jambudvipa and the Lavanasamudra there are 15 lunar mandalas (lunar diurnal circles) in
all."

The total north-south stretch across the lunar mandalas=180+ 330-510 Y.
(ii) Linkage of Lunar Mandala with Moon's Sidereal Course among the Stars:
Like the theory of two Suns, two Moons were considered to rise alternatively in southern quarter of Jambudvipa. As regards their motion in different lunar mandalas SP. 81 (Gaṇitānuyoga, pp. 284-286) states as:
"There are seven half-mandalas viz. 2nd, 4th, 6th, 8th, 10th, 12th and 14th in which Moon moves at the time of entering into the southern part (of Jambudvipa).

13 "There are 6 half-mandalas viz. 3rd, 5th, 7th, 9th, 11th, 13th and 67 67 the part of 15th (lunar mandala) in which Moon moves at the time of
entering into the northern part (of Jambudvipa)."
In this way, the first, candrayana (Moon's southern course among the stars) is over.

Thus the same Moon moves on 7 plus 667 i.e. 1367 half-mandalas in one candrayana (half the sidereal revolution of Moon). According to Jaina theory of two Suns and two Moons etc., the counter Moon also 13
moves on 13367 half-mandalas at the same time.
The total number of lunar mandalas in one candrayana (half the 13 sidereal revolution of moon)=137
We know that a quinquennial yuga (cycle) contains 67 naksatra months (lunar sidereal revolutions) or 134 candrāyanas.
Total number of lunar mandalas in a five-year cycle.
