❓ Frequently Asked Questions
What is Time Math in schedules and durations?
Time Math is the process of reading schedules and computing times by adding or subtracting time intervals, and by measuring how long something lasts.
How do you add a duration (for example, 2 hours 15 minutes) to a start time?
Add minutes first; if the sum is 60 or more, convert to hours and carry over. Then add hours and adjust for 24-hour wrap if needed.
How do you find the duration between a start and end time?
Subtract the start time from the end time. If the end time is earlier than the start, assume the end is on the next day and add 24 hours before subtracting.
How do you handle times that cross midnight?
Treat the end time as after midnight (the next day) and compute the difference, or use a 24-hour format to keep it simple.
How can you convert between hours/minutes and total minutes?
Total minutes = (hours × 60) + minutes. To convert back: hours = floor(totalMinutes / 60) and minutes = totalMinutes % 60.
