islamilaisilla

Islaamilaisilla refers to the Islamic calendar, also known as the Hijri calendar. It is used to determine the dates for Islamic holidays and events, and is based on the lunar cycle. The calendar is about 11 days shorter than the solar calendar used by most of the world.

The Islamic calendar is a lunisolar calendar, meaning it is based on both the cycles of the sun and moon. Each month begins on the sighting of the new moon, which can vary from year to year. This means that the dates of Islamic holidays can shift by a day or so from year to year, relative to the solar calendar.

The Islamic calendar has 12 months, which are named after different lunar cycles. The months are as follows: Muharram, Safar, Rabi' al-awwal, Rabi' al-thani, Jumada al-awwal, Jumada al-thani, Rajab, Sha'ban, Ramadan, Shawwal, Dhu al-Qadah, and Dhu al-Hijjah. Some of the most significant Islamic holidays include Ramadan, the holy month of fasting, and Eid al-Fitr, which marks the end of Ramadan.

Islaamilaisilla is also used to date events in Islamic history and is often expressed as "AH" (Anno Hijri", or "Year of the Hijra") as an alternative to the Common Era (CE) or Anno Domini (AD) dating system. This dating system is used to indicate dates in the Islamic calendar.

The Islamic calendar is used in many countries with significant Muslim populations, including Saudi Arabia, Iran, and Indonesia. It is an important part of the Islamic faith and culture, and is used to determine the timing of many significant events and celebrations.
