Kali (काली) is from the Sanskrit kāla (time, death, black).
Bengal's Kalighat temple in Kolkata is one of the 51 Shakti Peethas.
Kali 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 Kali reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
