Calculation Examples

Let’s go through two example calculations to illustrate how it works.

Example 1:

• Start Time: 08:00
• Break Duration (minutes): 30

Calculation Steps:

1. Enter 08:00 as the Start Time.
2. Enter 30 as the Break Duration.
3. Convert Start Time to minutes:
$8\times 60+0=480$minutes.
4. Calculate total minutes worked:
$480+480-30=930$minutes.
5. Convert back to hours and minutes:
$930÷60=15$hours and $930\mathrm{m}\mathrm{o}\mathrm{d}60=30$minutes.
6. Result: End Time: 15:30 or 3:30 PM.

Example 2:

• Start Time: 09:00
• Break Duration (minutes): 45

Calculation Steps:

1. Enter 09:00 as the Start Time.
2. Enter 45 as the Break Duration.
3. Convert Start Time to minutes:
$9\times 60+0=540$minutes.
4. Calculate total minutes worked:
$540+480-45=975$minutes.
5. Convert back to hours and minutes:
$975÷60=16$hours and $975\mathrm{m}\mathrm{o}\mathrm{d}60=15$minutes.
6. Result: End Time: 16:15 or 4:15 PM.
