Logical Reasoning
Clocks and calendars
Angles between clock hands and day-of-week problems.
Angle between the hands at H hours M minutes = |30H − 5.5M| degrees (take 360 minus it if more than 180).
The minute hand moves 6° per minute; the hour hand 0.5° per minute.
An ordinary year has 1 odd day, a leap year 2.
📌 Remember for the exam
- θ = |30H − 5.5M|
- Hands overlap 22 times in 24 hours
