Not sure if this is the intended interpretation and whether it is complete or if there is more behind it:
So, maybe somebody can give a clearer picture.
Maybe...
- the 24 rows present the 24 hours of a day
- the 100 columns represent 100 years in a century
- the 60 columns which are colored cyan (neglecting the white cells) represent the 60 minutes in an hour
- the white rows have a different lengths (i.e. number of columns) from 29 to 31
- from row 1 (counting from 0) to row 12 the lengths coincide with the number of days in the 12 months in a year (February with 29 days)
The magenta colored cells:
The 7th column (counting from 1) of the 11th white row:
This should probably represent November 7th, the date of posting this puzzle.
The 23rd column of the 20th row (counting from 0):
this should probably direct to the year 2023
In summary:
Topic: Date and Time
Date: Earth is moving around the sun in a circle (actually, ellipse)
Time: Hands of a clock running in circles
