Catalan Zodiac Rose S.XV

[quimqu]

It seems the scribe started with:
Janer Fabrer Marts Abril

Then corrected into (he didn't expect January to occur twice):
Janer Janeer Fabrer Marts Abril

And I think that the correction was wrong, it shoulb be Janer Janeer Marrts Marts Abril to keep 29 days distance from 
one entry to the next one.

Hello everyone,

Remember that there are 19 different tables in the manuscript.

I think it depends on when the lunar cycle starts for that table. For example, if it begins on January 20th or on January 1st, the calendar will be different, since the following 29 days of the lunar cycle would fall on different dates and could even occur twice within the same month. 

What I don’t understand is why, if a lunar cycle lasts 29 days, they used only 19 tables.
