To tell you “how long did I work” , I need at least:

  • A start time and end time (for one day), or
  • A start date and end date (for total work duration across days/years).

Without those, it’s impossible to compute your exact work duration.

If you’re asking about one day

You can calculate it like this:

  1. Convert both times to 24‑hour format (e.g., 9:00 AM → 9:00, 5:30 PM → 17:30).
  2. Subtract start from end:
    • Example: 17:30 − 9:00 = 8.5 hours (8 hours 30 minutes).
  3. Subtract any unpaid breaks (e.g., 30 minutes → 0.5 hours) if needed.

So if you tell me something like:

“I worked from 9:00 AM to 6:00 PM with a 1‑hour unpaid break,”

then your total work time is:

18:00−9:00=9 hours⇒9−1=8 hours.18:00-9:00=9\text{ hours}\quad \Rightarrow \quad 9-1=8\text{ hours}.18:00−9:00=9 hours⇒9−1=8 hours.

If you’re asking about total work experience

If you mean how long you’ve been working in your career , you’d:

  1. Take the earliest start date of your first job and the latest end date (or today, if still working).
  2. Use a work‑experience calculator or date‑difference tool to get years, months, and days.

For example:

Period| Duration
---|---
Jan 1, 2018 – Dec 31, 2022| 5 years
Jan 1, 2023 – Feb 5, 2026| 3 years 1 month

Total ≈ 8 years 1 month of work experience.

Quick HTML‑style table (as requested)

html

<table>
  <tr>
    <th>Scenario</th>
    <th>What you need to provide</th>
    <th>Example</th>
  </tr>
  <tr>
    <td>Hours worked in one day</td>
    <td>Start time, end time, and unpaid break</td>
    <td>9:00 AM – 6:00 PM, 1‑hour break</td>
  </tr>
  <tr>
    <td>Total career duration</td>
    <td>First job start date, last job end date (or “present”)</td>
    <td>Jan 1, 2018 – Feb 5, 2026</td>
  </tr>
</table>

Reply with either:

  • “From [start time] to [end time] with [X minutes] break,” or
  • “From [start date] to [end date] (or present),”

and I’ll tell you exactly how long you worked , in hours, days, or years.
