Åsta's name day is March 28 in Norway.
Åsta is a traditionally feminine name derived from Old Norse, where its meaning is often linked to "divine" or "beloved." Historically, it is a significant name in Scandinavian culture, particularly Norway, reflecting ancient naming conventions. In the USA, Åsta remains uncommon, primarily due to its distinct spelling and strong association with Nordic heritage. Its overall tone is strong, ancient, and profoundly elegant, conveying a sense of grounded resilience. The name's rarity in the States contributes to its unique and distinguished character. This firmly female name preserves a mythologically charged linguistic heritage.
