While in English such a system would pose a problem, since many ordinal numbers start with the same letters (first, fourth, fifth, etc.), the calendar's numerals are in [[Mandae]], which uses separate letters for each of the ordinal numbers up to twelve. Thus, the dantrian calendar might run into problems only after the twelfth revolution. | While in English such a system would pose a problem, since many ordinal numbers start with the same letters (first, fourth, fifth, etc.), the calendar's numerals are in [[Mandae]], which uses separate letters for each of the ordinal numbers up to twelve.
