Which country has the lowest value currency in the world?

TPO - This country uses its own calendar, is home to more than 20 UNESCO World Heritage Sites,... Its currency has the lowest value in the world. The devaluation of its currency is mainly due to many economic and political factors.

The correct answer is option A: The earliest appearance of the Iranian calendar dates back to the 2nd millennium BC, before the appearance of the Iranian prophet Zoroaster, the first to preserve the calendar was the Achaemenids. In recorded history, the Persians were very concerned about the importance of the calendar. They were among the first cultures to use a solar calendar and had long sought to access a solar power over the moon and the sun. The sun has always been a symbol in Iranian culture and is closely associated with the folklore of Cyrus the Great. It is now February 2025 (according to the Gregorian calendar) but the calendar on every desk, in every home of an Iranian will show the year 1403. Calculated astronomically for Iranian Standard Longitude (52.5°E or GMT + 3.5h), this is the Hijiri solar calendar, a calendar based on observation, unlike the Gregorian calendar, which is based on laws. Iran's use of its own calendar is not because the country is under embargo. The Muslim world has a common calendar called the Islamic calendar, but depending on observations and calculations, the calendars of different countries sometimes differ by a few days.
