The hands are at right angles to each other twice in every hour except that the only time between 2:00 and 3:00 is just after 2:27 and the only time between 8:00 and 9:00 is just after 8:27 ;

Between twelve o'clock midnight and twelve o'clock noon, the minute and hour hands of a clock are at right angles to each other 22 times. This occurs as the hands rotate, resulting in angles of 90 degrees and 270 degrees at various times. The positions can be calculated based on their respective speeds of rotation throughout the 12 hours.
