Complete CMAT Clocks & Calendars Formulas List
Below is a complete list of important CMAT Clocks & Calendars formulas for quick revision.
Clock Formulas
Clock Hand Speeds
- Minute Hand Speed = 6° per minute
- Hour Hand Speed = 0.5° per minute
- Second Hand Speed = 6° per second
Angle Moved by Minute Hand
Angle = 6 × M
where M is the number of minutes.
Angle Moved by Hour Hand
Angle = 30 × H + 0.5 × M
where:
- H = hours completed after 12
- M = minutes past the hour
Angle Between Hour and Minute Hands
Angle = |30H − 5.5M|
If the angle obtained is greater than 180°, subtract it from 360° to get the smaller angle.
Relative Speed of Clock Hands
Relative Speed = 5.5° per minute
This is used to solve coincidence and overtaking problems.
Number of Coincidences
- In 12 hours = 11 times
- In 24 hours = 22 times
Mirror Time Formula
Mirror Time = 11:60 − Given Time
Calendar Formulas
Odd Days
Odd Days = Total Days Mod 7
The remainder obtained after dividing total days by 7 is called the number of odd days.
Century Odd Days Table
| Century | Odd Days |
|---|---|
| 1600 / 2000 | 0 |
| 1700 / 2100 | 5 |
| 1800 / 2200 | 3 |
| 1900 / 2300 | 1 |
Leap Year Rules
A year is a leap year if:
- It is divisible by 400, OR
- It is divisible by 4 but not by 100.
Examples:
- 2000 → Leap Year
- 2024 → Leap Year
- 1900 → Not a Leap Year
Month Odd Days Table
| Month | Normal Year | Leap Year |
| January | 3 | 3 |
| February | 0 | 1 |
| March | 3 | 3 |
| April | 2 | 2 |
| May | 3 | 3 |
| June | 2 | 2 |
| July | 3 | 3 |
| August | 3 | 3 |
| September | 2 | 2 |
| October | 3 | 3 |
| November | 2 | 2 |
| December | 3 | 3 |
Day of the Week Formula
Weekday Index = (C + Y + L + M + D) mod 7
where:
- C = Century odd days
- Y = Odd days from years
- L = Leap year additions
- M = Month code
- D = Date number
Calendar Repetition Formulas
Weekday Shift in a Year
For a normal year:
Shift = 1 Odd Day
For a leap year:
Shift = 2 Odd Days
Calendar Repetition Condition
Two years will have the same calendar if:
- Both are either leap years or non-leap years.
- Total weekday shift is a multiple of 7.
28-Year Calendar Cycle
The Gregorian calendar follows a repeating cycle of:
28 Years
This is useful for identifying repeating calendars over long periods.
Leap Years Between Two Years
Number of Leap Years = ⌊Y/4⌋ − ⌊Y/100⌋ + ⌊Y/400⌋
For a range of years, calculate leap years up to the ending year and subtract the count up to the year before the starting year.
Important Shortcuts
Quick Anchor Date
1 January 2000 = Saturday
This is useful for solving modern calendar questions quickly.
Normal Year Calendar Repetition
Most normal-year calendars repeat after:
6 or 11 years, depending on the placement of leap years.
Leap Year Calendar Repetition
Leap-year calendars usually repeat after:
28 years
although some special cases may repeat earlier.
