Ramadan, the ninth month of the Islamic calendar, is the time when Muslims around the world fast for one month and break their fast after evening prayers by having an “iftar” meal.
In Iran, people marked the beginning of the Islamic holy month on Sunday by performing traditional rituals on the streets of the capital, Tehran.
Traditional or classic music was played, while crushed seeds of wild rue or Esfand were burned.
Esfand burning is a well-known cultural feature in Iran, which is believed to keep away negative energy.
The people participating also prepared sugar cubes for tea servings during the evenings of Ramadan.
Dates, sweet food and confectionary are consumed in higher quantities during the holy month.
There are an estimated 1.6 billion Muslims around the world, making up a majority in 49 countries.
