Next we realize that 314 must be considered as equal to 250 + 64 (not as the ugly 251 + 63):

Hb3-4	Hb3-5	Hb3-6 (753)
64 + 250 = 314

To accomplish this feat, where 100π is the sum of 8 squared and 10 times 5 squared (probably an irresistible equation for the number jugglers who created the rongorongo texts), we must find an extra day to add to those 63 (resulting from adding 5 to 58).

The natural place to search for the needed extra day is at the beginning of side a, and the glyphs there indeed support a reading where day 1 is beginning with Ha1-4:

Ha1-1	Ha1-2	Ha1-3	Ha1-4	Ha1-5	Ha1-6
0 (= day 64)			day 1
Ha1-7	Ha1-8	Ha1-9	Ha1-10	Ha1-11	Ha1-12
2			3
Ha1-13	Ha1-14	Ha1-15	Ha1-16	Ha1-17	Ha1-18
4			5

This way of reading the beginning of side a is placing Ha1-6, the 'midnight henua', in its proper position, as day number 1.
