### 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:**

- Enter
`08:00`

as the Start Time. - Enter
`30`

as the Break Duration. - Convert Start Time to minutes: $8\times 60+0=480$ minutes.
- Calculate total minutes worked: $480+480-30=930$ minutes.
- Convert back to hours and minutes: $930\xf760=15$ hours and $930\phantom{\rule{0ex}{0ex}}\phantom{\rule{0.6667em}{0ex}}\mathrm{m}\mathrm{o}\mathrm{d}\text{\hspace{0.17em}}\text{\hspace{0.17em}}60=30$ minutes.
- Result:
**End Time: 15:30**or 3:30 PM.

#### Example 2:

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

**Calculation Steps:**

- Enter
`09:00`

as the Start Time. - Enter
`45`

as the Break Duration. - Convert Start Time to minutes: $9\times 60+0=540$ minutes.
- Calculate total minutes worked: $540+480-45=975$ minutes.
- Convert back to hours and minutes: $975\xf760=16$hours and $975\phantom{\rule{0ex}{0ex}}\phantom{\rule{0.6667em}{0ex}}\mathrm{m}\mathrm{o}\mathrm{d}\text{\hspace{0.17em}}\text{\hspace{0.17em}}60=15$minutes.
- Result:
**End Time: 16:15**or 4:15 PM.
