Chaitra is from the Sanskrit चैत्र (Chaitra — first month of Hindu lunar calendar, spring season). Chaitra is one of the Sanskrit feminine names — central to traditional Hindu Vedic heritage. Sanskrit feminine name reflecting Hindu calendrical heritage.
Chaitra does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.

In Pythagorean numerology the letters of Chaitra reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
