What are mirror hours?

Mirror hours (or repeated hours) are times on the clock where the hours and minutes repeat, like 11:11 or 22:22. Noticing them often is a popular sign in numerology and spirituality: the repeated number is read as a message or a reminder about the moment you are living. There is no scientific evidence that they predict anything — but they are a useful invitation to pause and pay attention to your thoughts.

How to read a mirror hour

Notice what you were thinking or feeling when you saw the hour, read the meaning of the repeated number and ask how it relates to your current situation. The meaning is a prompt for reflection, not a prediction. If the same hour keeps appearing, it may point to a theme you are ready to work on.
