Here there are two exactly alike glyphs like this. In Saturday (Large Santiago) there was a rei miro too. Saturday is at the end of the week. Here we find two rei miro at the end of a (presumed) year.

 

In the calendar of the year (Small Santiago / London) a rei miro comes as the first glyph of all. But perhaps that period still belongs to the last part of the preceeding year.

 

However, there are more rei miro in the mentioned calendar of the year. Summer solstice is located (I believe) in what I call period no. 15. Both in periods nos.13-14 and in periods nos. 16-17 there are rei miro. So perhaps rei miro is used both at the start and at the end of periods.

 

In the (presumed) calendar of the year in Keiti we find rei miro in periods nos. 5, 7, 18 and 24. Obviously that in period no. 7 corresponds to the first rei miro in the Small Santiago / London calendar. Those in 5 and 18 are twins according to the surrounding glyphs. Could there be rei miro at the beginning (period no. 7), at the end (period no. 24) and at equinoxes (periods no. 5 and 18)?
