Determine Time Format

Earlier than performing any calculations, it is important to establish the format of the time values you are working with. Widespread time codecs embody:

  • 12-Hour Format (AM/PM)

    This format shows time in a 12-hour cycle, utilizing the designations AM (ante meridiem) for occasions earlier than midday and PM (publish meridiem) for occasions after midday. For instance, 9:30 AM or 4:15 PM.

  • 24-Hour Format

    Also referred to as navy time, this format shows time utilizing a 24-hour clock, starting from 00:00 to 23:59. For instance, 09:30 or 16:15.

  • Unix Timestamp

    Unix timestamps signify the variety of seconds which have elapsed since January 1, 1970, at 00:00:00 Coordinated Common Time (UTC). This format is often utilized in computing programs and programming.

  • Epoch Time

    Much like Unix timestamps, epoch time represents the variety of seconds which have handed since January 1, 1970, at 00:00:00 UTC, nevertheless it excludes the fractional seconds element. Epoch time is commonly utilized in database and programming functions.

As soon as you’ve got recognized the time format, be certain that each occasions you are calculating the distinction between are in the identical format. This can assist keep away from errors and guarantee correct outcomes.

Convert to a Commonplace Format

To make sure consistency and simplify calculations, it is usually useful to transform each occasions to a normal format. The commonest normal format is the 24-hour format (often known as navy time). This format eliminates any ambiguity related to AM/PM designations and permits for simpler subtraction and comparability of occasions.

  • Convert 12-Hour Instances to 24-Hour Format

    To transform a 12-hour time to 24-hour format, merely add 12 to the hour worth if it is within the PM vary. For instance, 4:30 PM turns into 16:30 in 24-hour format.
