On 5 January 1975, the 12-bit field that had been used for dates in the TOPS-10 operating system for DEC PDP-10 computers overflowed, in a bug known as "DATE75". The field value was calculated by taking the number of years since 1964, multiplying by 12, adding the number of months since January, multiplying by 31, and adding the number of days since the start of the month; putting 2 12 − 1 ...
The leap year problem (also known as the leap year bug or the leap day bug) is a problem for both digital (computer-related) and non-digital documentation and data storage situations which results from errors in the calculation of which years are leap years, or from manipulating dates without regard to the difference between leap years and common years.
The condition/decision criterion does not guarantee the coverage of all conditions in the module because in many test cases, some conditions of a decision are masked by the other conditions. Using the modified condition/decision criterion, each condition must be shown to be able to act on the decision outcome by itself, everything else being ...
As mentioned, leap years typically take place every four years. That means the next leap years coming up after 2024 are 2028, 2032, 2036, 2040, 2044 and 2048. But again, it's not quite that easy.
It is the same as if 4 mod year = 0 and 100 mod year ≠ 0, then not a leap year, unless 400 mod year = 0, then it is a leap year. Sanity check {{IsLeapYear|2000}} → 1: 2000 AD is effectively a leap year (in both the Julian and Gregorian calendars) .
A year may be a leap year if it is evenly divisible by 4. Years divisible by 100 (century years such as 1900 or 2000) cannot be leap years unless they are also divisible by 400. (For this reason ...
