A
striking clock (also known as
chiming clock) is a
clock that sounds the
hours audibly on a
bell or
gong. In 12-hour striking, used most commonly in striking clocks today, the clock strikes once at one a.m., twice at two a.m., continuing in this way up to twelve times at 12 noon, then starts again, striking once at one p.m., twice at two p.m., up to twelve times at 12 midnight.
