The first row has the Introductory glyph. All important dates have one preceding the calendric count, basically it says:
"Here comes an important date".

From rows 2 to 6 all the glyphs represent different time periods, their names and duration in days are described in the table. These glyphs all have numbers preceding them which indicate how many of these time periods (Baktun = 144,000 days, Katun = 7,200 days, Tun = 360 days, Uinal = 20 days, Kin = 1 day) have passed since the Maya Calendar's starting date, Aug. 13, 3114 BC.

The glyphs and numbers of the last two rows (7,8) show the denomination of the day and the month of the Calendar Round, which is the current 52 year Maya time period.

The correlation factor used in all our calculations is Thompson's 584,285
