The calendar for the night (in somewhat different versions in the texts of A, H, P and Q) has what appears to be similar end glyphs (toa or rau hei):
DUSK TO MIDNIGHT
-
Aa1-37 Aa1-38 Aa1-39 Aa1-40 Aa1-41 Aa1-42
Ha5-37 Ha5-38 Ha5-39 Ha5-40 Ha5-41 Ha5-42 Ha5-43
Pa5-19 Pa5-20 Pa5-21 Pa5-22 Pa5-23 Pa5-24 Pa5-25
Qa5-27 Qa5-28 Qa5-29 Qa5-30 Qa5-31 Qa5-32 Qa5-33
MIDNIGHT TO DAWN
-
Aa1-43 Aa1-44 Aa1-45 Aa1-46 Aa1-47 Aa1-48
- -
Ha5-44 Ha5-45 Ha5-46 Ha5-47 Ha5-48
- -
Pa5-26 Pa5-27 Pa5-28 Pa5-29 Pa5-30 Pa5-31
-
Qa5-34 Qa5-35 Qa5-36 Qa5-37 Qa5-38 Qa5-39

These contrast with the corresponding end glyphs (tapa mea) of the daytime calendars, e.g. in A:

Aa1-17 Aa1-19 Aa1-21 Aa1-23 Aa1-25
Aa1-27 Aa1-29 Aa1-31 Aa1-34 Aa1-36

It would then not be surprising to find also in a calendar for the year two different kinds of end glyphs, e.g.:

Ka2-14 Ka4-15
