In Zoroastrianism, Spənta Ārmaiti (Avestan 𐬯𐬞𐬆𐬧𐬙𐬀 𐬁𐬭𐬨𐬀𐬌𐬙𐬌 for "creative Harmony" and later "holy devotion") is one of the Amesha Spentas, the six creative or divine manifestations of Wisdom and Ahura Mazda. Spenta suggests a creative and constructive quality or force while Armaiti means regulative thought originally alluding to the physical laws of nature (i.e. Physics). While older sources present the Amesha Spentas more as abstract entities in later sources, Spenta comes to denote holiness and sanctity and Spenta Armaiti is personified as a female divinity thus its association with the female virtue of devotion (to family, husband, and child). She is associated with earth and Mother Nature.
In the Zoroastrian calendar, she is associated with the twelfth month (Persian: سپندارمذ Spendārmad) and the fifth day of the month. The fifth day of the twelfth month is hence her holy day, Sepandārmazgān. Sepandārmazgān is an ancient festival to celebrate eternal love. Iranian lovers give each other gifts on this day.
