Tajikistan considers itself a secular state with a constitution providing for freedom of religion. Sunni Islam of the Hanafi school has been officially recognised by the government since 2009. The government has declared two Islamic holidays, Eid ul-Fitr and Eid al-Adha, as state holidays. According to a US State Department release and Pew research group, the population of Tajikistan is 98% Muslim. Approximately 87%–95% of them are Sunni and roughly 3% are Shia and roughly 7% are non-denominational Muslims. The remaining 2% of the population are followers of Russian Orthodoxy, Protestantism, Zoroastrianism and Buddhism. Many Muslims fast during Ramadan, although only about one third in the countryside and 10% in the cities observe daily prayer and dietary restrictions.
