Michal (מִיכַל) is the Hebrew feminine of Michael — meaning "who is like God." Michal was the younger daughter of King Saul and the first wife of King David, who saved his life by helping him escape Saul.
Michal is widely used in modern Israel.
Michal 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 Michal reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
