Convert 11:39 PM

When it comes to the 11:39 p.m. time conversion, the minutes (the two digits after the colon) never change. To obtain the 24-hour clock time equivalent of 11:39 P.M. consider only the number of hours (the two digits before the colon), then apply these rules:

  • If the period is “AM” and the number of hours is 12, then 12 changes to 00. Remove “AM”.

    As the period is not AM, this rule does not apply.

  • If the period is “AM” and the number of hours is in the interval [1;11], then the hour remains the same. Remove “AM”.

    As the period is not AM, this condition does not pertain.

  • If the period is “PM” and the number of hours is 12, then 12 remains 12. Remove “PM”.

    As the number of hours is 11, this case is not relevant.

  • If the period is “PM” and the number of hours is in the interval [1;11], then add 12. Remove “PM”.

    As the period is PM and the number of hours is 11, process only this rule.
