Gb3-24 is glyph 314 counted from the beginning of side a and Gb3-30 is glyph 91 counted from the beginning of side b. In the center of this week is Gb3-27, where Regulus culminated at midnight, an event which at the time of the Hyades Gate occurred in February 1 (32):

This was 100 days before Pollux rose with the Sun and transferring the dates at the time of the Hyades Gate to the C text - using the general resemblance between Gb3-27 and Cb4-19 - we can guess C possibly could have been created by using a year measuring 350 days:

Cb4-17	Cb4-18	Cb4-19	Cb4-20 (483)
May 10	11 (*51 = *115 - 64)	12 (132 = *52 + 80)	13 (133 = 483 - 350)

... Thus the regular old Roman year ended with Februarius 23 and it was 350 nights long, 25 fortnights. Then followed 5 extra nights, or as the Romans saw it 5 + 1 = 6 nights in order to include March 1, the first day of the new regular year ...

Furthermore, Ca13-6 could allude to day 136 - the measure for the distance from January 1 to May 16, when in rongorongo times the Pleiades rose heliacally 8 weeks counted from the beginning of the text:

It should be noticed that 400 = 136 + 264:
