 The `-` (dash) and `.` (dot) characters are not legal in Cypher variables.
-Names with a `-` in them must be enclosed within backticks.
+Names containing a `-` or that begin with a numeric character must be enclosed within backticks.
 For example, `CREATE DATABASE ++`main-db`++` is a valid database name.
 Database names are the only identifier for which dots do not need to be quoted.
 For example `main.db` is a valid database name.
