The Old Calendar (旧暦 Kyūreki) is the calendar that was used in the Nanoha universe during the Ancient Belkan times, before the adoption of the New Calendar. The only certain date in the OC is the destruction of Belka in the year 462,[1] and its exact relation to the New Calendar and the Gregorian calendar is unclear.

In English translations, Old Calendar is sometimes referred to as "Lunar Calendar", because the kanjis used in it are the same as in the lunisolar calendar that was used in Japan until 1873. It is unclear, however, whether the Old Calendar in Nanoha was also based on the lunar cycles, since the kanjis themselves don't actually refer to the moon.
