Aayan is of uncertain origin; it is used mainly in Muslim families from South Asia and is usually explained as "gift of God", while some connect it to the Arabic word for a period of time. The spelling with a double a reflects the long first vowel, and Ayaan is the more common form in the US. Aayan reached the top 1000 exactly at number 1000 in 2019 and ranks number 1571 among American boys' names in 2025.
