The Islamic calendar, Muslim calendar or Hijri calendar is a lunar calendar consisting of 12 lunar months in a year of 354 or 355 days.

Being a purely lunar calendar, it is not synchronized with the seasons. With an annual drift of 10 or 11 days, the seasonal relation repeats about every 33 Islamic years.

It is used to date events in many Muslim countries (concurrently with the Gregorian calendar), and used by Muslims everywhere to determine the proper days on which to observe the annual fast (see Ramadan) and to attend Hajj, in addition to celebrate other Islamic holidays and festivals.

The first year was the Islamic year beginning in 622 CE during which the emigration of Muhammad from Mecca to Medina, known as the Hijra, occurred. Each numbered year is designated either H for Hijra or AH for the Latin anno Hegirae (in the year of the Hijra), hence, Muslims typically call their calendar the Hijri calendar.

The current Islamic year is 1433 AH, from approximately 26 November 2011 (evening) to 14 November 2012 (evening).

Zakir Abdul Karim Naik (Urdu: ذاکر عبدالکریم نائیک; born 18 October 1965) is an Indian public speaker on the subject of Islam and comparative religion. He is the founder and president of the Islamic Research Foundation (IRF), a non-profit organisation that owns the Peace TV channel based in Dubai, UAE. He is sometimes referred to as a televangelist. Before becoming a public speaker, he trained as a doctor. He has written two booklets on Islam and comparative religion. He is regarded as an exponent of the Salafi ideology; he places a strong emphasis on individual scholarship and the rejection of "blind Taqlid", which has led him to repudiate the relevance of sectarian or Madh'hab designations, all the while reaffirming their importance.

Zakir Abdul Karim Naik was born on 18 October 1965 in Mumbai, India. He attended St. Peter's High School in Mumbai. Later he enrolled at Kishinchand Chellaram College, before studying medicine at Topiwala National Medical College and Nair Hospital and later the University of Mumbai, where he obtained a Bachelor of Medicine and Surgery (MBBS). His wife, Farhat Naik, works for the women's section of the IRF.

Maulana Tariq Jameel (Urdu: مولانا طارق جمیل) (born 1953) is an Islamic scholar from Pakistan. His native town is Tulambah near Mian Channu. His father was an agriculturist who belonged to the Muslim Rajputs community.^{[citation needed]}

Tariq Jameel was born and raised in Mian Channu. In his childhood he lived a relatively modest life but religion was not a major part of his life and his family in particular. It wasn't until he pursued his M.B.B.S. in Lahore that his focus shifted towards Islam. After completing his Higher Secondary School education (a.k.a. F.Sc in some regions of Pakistan) in pre-medical (equivalent to A 'levels') from Government College, Lahore, he took admission in King Edward Medical College in Lahore. He intended to do his M.B.B.S., but he soon switched to Islamic education. He then went on to receive Islamic education from Jamia Arabia, Raiwind (near Lahore), Pakistan where he studied Quran, Hadith, Sharia, Tasawwuf, logic and Fiqh.^{[citation needed]}

His proclivity towards Islam grew during hostel life in Lahore and can mainly be attributed to the group members of Tablighi Jamaat who he became friends with during his college life.^{[citation needed]}
