February 28 (59)	29	March 1

March 1 will then be day 61 and the presence of number 61 in H / P / Q becomes more understandable - it suggests a year with 6 * 61 = 366 days, a leap year.

Ca13-4	Ca13-5	Ca13-6

12 * 29½ = 354 and hakaariki are at left in Ca13-11, they have presumably done their work. 4 nights later is a niu, and then a fresh vae which connects to the earlier such glyphs (see the previous page). March 14 can be written 3-14:

Ca13-16 (359)	Ca13-17	Ca13-18
March 14 (π)	15	16

If we should add a Mensis Intercalaris to February 23 (54) in an ordinary year we will reach March 17. 54 + 22 = 76 = 59 + 17. But by counting also Ca13-2 (February 29) we will reach March 16 (at Ca13-18). This should be done every 4th year. In ¾ of the years Ca13-2 could theoretically regarde be at March 1 and Ca13-18 would then represent March 17.

Ca13-19	Ca13-20 (363)
March 17 (77)	18 (443)

This is the end of the 13th glyph line. Only half a glyph is drawn beyond the vero (spear) in Ca13-19 and 15 * 29½ = 442½.
