Today is Tuesday, Feb. 23 coincident with the Persian day of love (the oldest Valentine in the world), which is named Sepandārmazgān.

Iran PressIran News: Sepandārmazgān or Esfandegān is an ancient Iranian festival with Zoroastrian roots dating back to the Achaemenid Empire, the first Persian Empire. This festival is widely known as the Persian Day of Love, although it is celebrated in its neighboring Persian-speaking countries as well such as Afghanistan and Tajikistan.

According to the testimony of al-Biruni, in the 11th century CE, there was a festival when the names of the day and the month were the same. The deity Spandarmad protected the Earth and the good, chaste, and beneficent wife who loves her husband. According to him, the festival used to be dedicated to women, and men would make them 'liberal presents', and the custom was still flourishing in some districts of Fahla. 

Also, Tommorrow (Feb. 24) is the birthday of Muhammad ibn Muḥammad ibn Muḥammad ibn al-Ḥasan al-Ṭūsī, better known as Nasir al-Din al-Tusi, the Persian polymath, architect, philosopher, physician, scientist, and theologian.

Nasir al-Din Tusi was the most celebrated scholar of the 13th century in Islamic lands. Thomas Aquinas and Roger Bacon were his contemporaries in the West. He is often considered the creator of trigonometry as a mathematical discipline in its own right.

ّFor this purpose, the National Engineer's Day is celebrated in Iran every year on Feb. 24. A special commemorating ceremony is held to honor the efforts and achievements of the Iranian engineers.

Celebration of National Engineer's Day commemorates the birthday of Nasir al-Din al-Tusi.
