Saba (صبا) is the Arabic word for the "east morning breeze" — the gentle wind associated with dawn and lovers in classical Arabic poetry. Also the Arabic name for the kingdom of Sheba (1 Kings 10).
Saba Qamar (born 1984) is the Pakistani actress.
Saba 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 Saba reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
