To determine how many hours were worked, the best approach is to use a method or tool that tracks work hours effectively. Common ways include:

• Using time tracking software or apps (like Toggl Track, Clockify, or Work Log apps) which record start and end times automatically and calculate total hours worked.
• Manual methods such as pen and paper or Excel timesheets, where start and end times are logged and summed up.
• Digital timesheets or automatic time clocks that can also handle breaks, overtime, and wages.

If you want to find out your exact hours worked for a given period, you would typically check your timesheet records, time tracking app logs, or any manual tracking you have done. Without specific data or records from your side, it's not possible to calculate the exact hours here. If you use a digital tool or app, I can guide you through how to check or calculate your total hours worked. If you need recommendations for tools to start tracking, I can provide those as well. Would you like help with using a specific app or method to calculate your hours worked? Or if you provide details about your work hours for a time range, I can help calculate the total?
