Analyze Clock Time

Enter any clock time and it breaks the value down into every common representation: 12-hour and 24-hour format, a plain-language conversational reading, minutes since midnight, day progress, time remaining until midnight, and how the time maps to the hands of an analog clock, including the angle between them. One input, every conversion you would otherwise compute separately.

Minutes since midnight divided by 1,440, the number of minutes in a day. Noon is exactly 50 percent, 6:00 PM is 75 percent. The same proportion is what spreadsheets use internally for time arithmetic, which makes the figure handy when debugging Excel or Google Sheets time formulas.

The minute hand moves 6 degrees per minute (360/60). The hour hand moves 30 degrees per hour plus 0.5 degrees per minute, so at 3:30 it points halfway between 3 and 4, at 105 degrees. The angle between the hands is the difference, taking the smaller of the two possible arcs. These formulas are a staple of programming interview puzzles, and the tool doubles as a quick checker for them.

Students checking time-conversion homework, developers debugging timestamp math and cron schedules, teachers building worksheets, and anyone converting between 12-hour and 24-hour conventions, for example when reading international timetables or writing documentation for audiences used to a different format.

Yes, including the two cases people most often get wrong: midnight is 12:00 AM and 00:00 in 24-hour format (zero seconds elapsed), and noon is 12:00 PM and 12:00. The AM/PM labels around these edges follow the standard convention used by airlines and operating systems.
