This is Thursday:

Thursday is the day of thunder and therefore presumably of rain and lightning. Twins (glyph no. 4 from the left) signify fertility and without rain no growth.

Rain and things growing means that the period of hunger is over. Time for feasting. Glyphs nos. 5 and 7 perhaps are signs indicating 'kava' (= ginger on Easter Island). And glyphs nos. 3, 6 and 8 probably show people sitting down and eating. At first though the Gods must be given their share of the best, perhaps illustrated in glyph no. 2.

And glyph no. 9? Some of the global myths about twins talk about one of the twins being changed into a star. To get there presumably he must fly.
