We have so far ascertained there probably was meant to be a continuity from side a to side b. Furthermore, if there was a qualitative difference between side a and side b it could have been the time frame, for instance:
| side a |
modern calendar beginning with March 21 |
| side b |
ancient calendar beginning with the 1st point of Aries |
The end of side a contains a pair of Rogo figures, suggesting the time when a new year was about to begin:

If the Julian or some other Roman calendar was described on side b of the tablet, we maybe should investigate what conclusions we could draw from that:
... The Julian calendar introduced in 46 B.C. by Caesar changed the earlier 355 day long regular calendar by increasing the length of 7 of the months:

'The ordinary year in the previous Roman calendar consisted of 12 months, for a total of 355 days. In addition, a 27-day intercalary month, the Mensis Intercalaris, was sometimes inserted between February and March. This intercalary month was formed by inserting 22 days after the first 23 or 24 days of February; the last five days of February, which counted down toward the start of March, became the last five days of Intercalaris. The net effect was to add 22 or 23 days to the year, forming an intercalary year of 377 or 378 days.'

For instance should this old Roman calendar begin not at Cb1-1 but a week (355 - 348 days) earlier, where the Gregorian calendar had its day number 100 and where October 11 (which was its corresponding nakshatra date) indicated 100 nights remained to day 364:
