Numerologists believe that events linked to the time 11:11 appear more often than can be explained by chance or coincidence. This belief is related to the concept of synchronicity. Some authors claim that seeing 11:11 on a clock is an auspicious sign. Others claim that 11:11 signals a spirit presence. The belief that the time 11:11 has mystical powers has been adopted by believers in New Age philosophies. However, skeptics say that Uri Geller's examples of 11:11 phenomena in world events are examples of post-hoc reasoning and confirmation bias.
