The days making up a tenday did not have formal names. If precision was required, the number of the day and the number of the tenday were used, as in, "the fourth day of the first tenday of Flamerule".[5] Days of the month were typically written as the numerical date followed by the month name, for example, "15 Hammer" or "15th Hammer".[5][6] Informally or poetically this could be spoken or written as "the 15th of Deepwinter".[3][6]
