Where is the location of the equator in valor map

[HeeroX]

I would like to know where is the exact location of the equator in valor world map. I would like to use it to make my excel file more precise as it could be, removing all +/- seconds difference.

The Valor world is round. I don't know if the smaller worlds are intact yet, but this is how the layout used to be:
00 01 02 03 04
10 11 12 13 14
20 21 22 23 24
30 31 32 33 34
40 41 42 43 44
So to answer your question, R22 is dead center
