Usage notes

The word bidaily does not appear in most English-language dictionaries. Additionally, confusion may arise about whether bidaily means every two days or two times per day; it is therefore recommended to use more a common and unambiguous term such as semi-daily, twice-daily, or twice a day instead. (See usage notes for biweekly, bimonthly, and biannually.)
