Which country has the lowest-valued currency in the world?

TPO - This country uses its own calendar, has more than 20 UNESCO World Heritage sites, and its currency has the lowest value in the world. The devaluation of this currency mainly stems from a variety of economic and political factors.

The correct answer is A: The earliest appearance of the Iranian calendar dates back to the 2nd millennium BC, before the appearance of the Iranian Zoroastrian prophets. The first to maintain a calendar were the Achaemenids. Historically, the Persians were very interested in the importance of calendars. They were among the first cultures to use a solar calendar and had long sought to approach a solar energy on the moon and yin and yang. The sun has always been a symbol in Iranian culture and is closely associated with folklore about Cyrus the Great. It is now February 2025 (according to the Gregorian calendar), but the calendar on every desk in every Iranian home will show the year 1403. Calculated astronomically for the standard Iranian time of meridian (52.5°E or GMT + 3.5h), this is the Hijiri solar calendar, an observational calendar, unlike the Gregorian calendar, which is based on rules. Iran's use of its own calendar is not due to sanctions. The Islamic world has a common calendar called the Islamic calendar, but depending on observations and calculations, the Islamic calendars of different countries sometimes differ by a few days.
