The official announcement was made by a team of senior Muslim clerics led by PV Suhaib Moulavi after the sighting of the moon in Kozhikode on Friday evening.
Muslims in Kerala constitute 88.73 lakh of the 3.30 crore population.
Ramadan is the ninth month in the Islamic (Hijri) calendar. It is the most holy month in the calendar for Muslims as it is believed the Quran was revealed to Prophet Mohammed during Ramadan.
During this month, Muslims do not consume any food or liquid between fajr and maghrib prayers (at dawn and sunset), not even water.
Ramadan isn't just about fasting from food, it is primarily about being more pious and seeking spiritual closeness to God.
Fasting during Ramadan not only encourages abstaining from food but also from evil actions, thoughts and words.
Ramadan is a time for spiritual reflection and devoting themselves to worship and pray to Allah.
The conclusion of Ramadan is marked with a major celebration known as Eid ul-Fitr (or Eid al-Fitr), the Feast of Fast-Breaking. It starts the day after Ramadan ends and lasts for three days.
