In the Muslim world, the calendar is based on the cycles of the moon. The Hijri or Islamic lunar calendar consists of twelve months of 29 or 30 days – depending on the moon phase- and is used to pinpoint the days for Islamic holidays. In contrast to the solar calendar, which is used in the west, the months of the lunar calendar change annually by a difference of -10 to -12 days. As a result, each month always falls on a different season and therefore varies from the Gregorian Calendar.
TONDA HIJRI PERPETUAL CALENDAR PLATINUM SLATE GREEN
The Parmigiani Fleurier Tonda Hijri Perpetual Calendar takes all this into account, with its innovative mechanism developed entirely in-house as a result of Michel Parmigiani’s work with an antique Arabic calendar pocket watch. The counter at 12 o’clock displays the 30-year cycle, with abundant years indicated in green-colored script. The counter at 3 o’clock displays, using a hand, the month of the Islamic calendar, with the holy month of Ramadan indicated in red script. At 6 o’clock, an aventurine moon disc with polished moons shows the phase of the moon in the Northern Hemisphere. Finally, the counter at 9 o’clock displays the date, with a circular aperture revealing a white marker if the month has 29 days and a sand-colored marker if the month has 30 days.
