In order to reach winter solstice at Saturn, the calendar needs to be counted correctly. 13 * 28 = 364 is one possibility. Jupiter would then begin with day 4 * 56 + 1 = 225 (= 15 * 15) and end at day 5 * 56 = 280. Venus will rule from day 281 to day 280 + 56 = 336. Saturn will get only half a double-month, reigning at the end of the year from day 337 up to (but not including) day 365. 13 will come to mean death.

Jupiter represents the last phase of the sun, and when he disappears first Venus and then Saturn takes over. Sun is not present for more than 10 months.

In H we can identify when his half-time has been reached. The end of the first half is with day number 150, and a clear sign of the break in time can be seen in Ha9-2:

glyph numbers and days are counted from Ha1-4

Ha9-2	Ha9-3	Ha9-4 (450)	Ha9-5	Ha9-6	Ha9-7
150			151

The months are here evidently measured as 30 days long. A fat henua (Ha9-4) says the season of growing has ended, there will be no more 'eating'. The preceding manu rere exhibits a Y-formed 'hand' (meaning 'straw').
