If you happen to look at the clock when they show same figures for hours and minutes (10:10; 11:11, 23:23 etc.) you can make a wish. But, you cannot do it on purpose.
For example, if you have seen that it is 11:10 and you keep watching at the clock until it is 11:11, in this case the wish will not come true.

If a clock which has not been working suddenly chimes, there will be a death in the family.
