John Gruber is the creator of Markdown.
He describes the syntax here:
https://daringfireball.net/projects/markdown/syntax

headers

https://daringfireball.net/projects/markdown/syntax#header

Atx-style headers use 1-6 hash characters at the start
of the line, corresponding to header levels 1-6.

=> that means header level 6 is the maximum level (vim and bat also do not highlight
level 7 headings)

But there are also "Setext-style headers" that can only create
level 1 and 2 headers.
