Indo-Persian culture refers to a cultural synthesis present in the Indian subcontinent, characterized by the absorption or integration of Persian aspects into the various cultures of Pakistan, India and Bangladesh. The first large-scale introduction of Persian influence and culture to the Indian subcontinent was by Muslim rulers of Turkic and Afghan origin with Persianate societies and Persianized cultures. This socio-cultural synthesis arose steadily through the Delhi Sultanate from the 13th to 16th centuries, and the Mughal Empire from then onwards until the 19th century. Various Muslim Turko-Persian rulers, such as the 11th-century Sultan Mahmud Ghaznavi, rapidly pushed for the heavy Persianization of conquered territories in northwestern India, where Islamic influence was also firmly established.

Persian literature comprises oral compositions and written texts in the Persian language and is one of the world's oldest literatures. It spans over two-and-a-half millennia. Its sources have been within Greater Iran including present-day Iran, Iraq, Afghanistan, the Caucasus, and Turkey, regions of Central Asia and South Asia where the Persian language has historically been either the native or official language. For example, Rumi, one of the best-loved Persian poets, born in Balkh or Wakhsh, wrote in Persian and lived in Konya, at that time the capital of the Seljuks in Anatolia. The Ghaznavids conquered large territories in Central and South Asia and adopted Persian as their court language. There is thus Persian literature from Iran, Mesopotamia, Azerbaijan, the wider Caucasus, Turkey, Pakistan, Bangladesh, India, Tajikistan and other parts of Central Asia. Not all Persian literature is written in Persian, as some consider works written by ethnic Persians or Iranians in other languages, such as Greek and Arabic, to be included. At the same time, not all literature written in Persian is written by ethnic Persians or Iranians, as Turkic, Caucasian, and Indic poets and writers have also used the Persian language in the environment of Persianate cultures.

Persian mythology or Iranian mythology is the body of the myths originally told by ancient Persians and other Iranian peoples, and a genre of Ancient Persian folklore. These stories concern the origin and nature of the world, the lives and activities of deities, heroes, and mythological creatures, and the origins and significance of the ancient Persians' own cult and ritual practices. Modern scholars study the myths to shed light on the religious and political institutions of not only modern-day Iran but the Greater Iran, which includes regions of West Asia, Central Asia, South Asia and Transcaucasia where Iranian culture has had significant influence. Historically, these were regions long ruled by dynasties of various Iranian empires, that incorporated considerable aspects of Persian culture through extensive contact with them, or where sufficient Iranian peoples settled to still maintain communities who patronize their respective cultures. It roughly corresponds to the Iranian plateau and its bordering plains. The Encyclopædia Iranica uses the term Iranian Cultural Continent for this region.

It combines martial arts, calisthenics, strength training and music. Recognized by UNESCO as the world's longest-running form of such training, it fuses elements of pre-Islamic Persian culture with the spirituality of Shia Islam and sufism.

Yaldā Night or Chelleh Night is an Iranian Northern Hemisphere's winter solstice festival celebrated on the "longest and darkest night of the year." According to the calendar, this corresponds to the night of December 20/21 (±1) in the Gregorian calendar, and to the night between the last day of the ninth month (Azar) and the first day of the tenth month (Dey) of the Iranian civil calendar. The longest and darkest night of the year is a time when friends and family gather together to eat, drink and read poetry and Shahnameh until well after midnight. Fruits and nuts are eaten and pomegranates and watermelons are particularly significant. The red color in these fruits symbolizes the crimson hues of dawn and glow of life. The poems of Divan-e Hafez, which can be found in the bookcases of most Iranian families, are read or recited on various occasions such as this festival and Nowruz. Shab-e Yalda was officially added to Iran's List of National Treasures in a special ceremony in 2008.
