O.G. Cassani and John H. Conway have published an (aggravatingly closed-access) article about how to fix ordinals so we can start counting at 0 instead of 1, in the Mathematical Intelligencer. They call it 'Neumbering': https://link.springer.com/article/10.1007/s00283-017-9720-3

Long story short: instead of "first, second, third", go "zero'd, one'd, two'd".

I will endeavour to do so.
