📋 HOW TO USE — STEP BY STEP
1. Start Time: Enter when your shift, task, or period begins (24-hour or 12-hour depending on browser).
2. End Time: Enter when your shift, task, or period ends.
3. Break Duration: Enter total break time in minutes (lunch, rest, etc.). Breaks are subtracted from total hours.
4. Calculation Mode: Choose Same Day for a regular shift, Overnight if end time is past midnight, or Multi-Day to multiply across several days.
5. Number of Days: Only used in Multi-Day mode. Enter how many days the same shift pattern repeats.
6. Hourly Rate: Optional. Enter your rate per hour (any currency) and the tool will calculate estimated gross earnings.
📊 UNDERSTANDING THE RESULTS
Total Duration: Raw time between start and end, ignoring breaks.
Net Work Hours: Duration minus break time — the actual billable or paid hours.
Decimal Hours: Hours expressed as a decimal (e.g., 7h 30m = 7.50). Useful for timesheets and payroll systems.
Total Minutes: The complete duration in minutes — helpful for precise records.
Overtime (est.): Hours exceeding 8 hours/day standard. Shown as informational — actual OT rules vary by employer and country.
Estimated Pay: Gross pay at your specified hourly rate. Does not include taxes, deductions, or overtime premiums.
⚡ FORMULA & CALCULATION METHOD
Basic Formula: Duration = End Time − Start Time. If overnight: Duration = (24:00 − Start) + End. Net Hours = Duration − Break Minutes ÷ 60.
Multi-Day: Net Hours per day × Number of Days = Total Net Hours.
Decimal Conversion: Decimal Hours = Total Minutes ÷ 60. Example: 7h 45m = 465 min ÷ 60 = 7.75 hours.
Estimated Pay: Gross Pay = Net Decimal Hours × Hourly Rate. Multi-day: Total Net Hours × Hourly Rate.
