Frequently Asked Questions
How is the angle between clock hands calculated?
The angle is calculated by finding the positions of both hands and taking the absolute difference. The minute hand moves 6° per minute, and the hour hand moves 30° per hour plus 0.5° per minute. The smaller angle between the hands is always returned (0-180°).
What's the difference between degrees and radians?
Degrees are the common unit for measuring angles (360° in a full circle), while radians are the mathematical unit (2π radians in a full circle). 1 radian equals approximately 57.3 degrees. The tool can display angles in either format or both.
When do clock hands overlap?
Clock hands overlap approximately every 65 minutes, not every hour. The exact times vary, but they occur at times like 12:00, 1:05, 2:10, 3:15, etc. The tool can help you find these special times by calculating when the angle between hands is 0°.
Can I use this tool for programming clock applications?
Yes, the tool is perfect for programming clock applications, games, and time-based algorithms. It provides precise angle calculations and multiple output formats that can be directly used in code for creating digital clocks, analog clock displays, and time-based animations.
How accurate are the angle calculations?
The calculations are very accurate and include second precision. The tool accounts for the continuous movement of both hands, including the hour hand's movement between hour marks. All calculations are done with high precision to ensure accuracy.
What's the maximum angle between clock hands?
The maximum angle between clock hands is 180°. This occurs when the hands are directly opposite each other, such as at 6:00 (180°) or 12:30 (165°). The tool always returns the smaller angle, so you'll never see angles greater than 180°.
