Hours Calculator | Time Duration Calculator

Calculating time duration between two points is essential in daily life, work scheduling, project management, and travel planning. The Hours Calculator allows you to quickly find the difference between two times, convert hours to minutes or seconds, and manage your time efficiently without manual errors.

Why Use an Hours Calculator?

• Time Management: Calculate work hours, overtime, or study durations accurately.
• Travel Planning: Determine journey durations and arrival times.
• Project Scheduling: Track task durations and deadlines effectively.
• Convenience: Avoid manual calculations and reduce mistakes.

Formulas Used

• Time Duration (Hours): Hours = End Time − Start Time
• Convert Hours to Minutes: Minutes = Hours × 60
• Convert Hours to Seconds: Seconds = Hours × 3600
• Convert Minutes to Hours: Hours = Minutes ÷ 60
• Convert Seconds to Hours: Hours = Seconds ÷ 3600

How the Hours Calculator Works

1. Enter the start time and end time in 24-hour or 12-hour format.
2. Click Calculate Duration to get the difference in hours, minutes, and seconds.
3. Optionally, convert the total hours into minutes or seconds using the conversion formulas above.
4. The calculator automatically handles overnight durations (e.g., 10 PM to 2 AM) and provides accurate results.

Step-by-Step Example 1: Calculate Duration

Problem: Start time: 09:30 AM, End time: 02:15 PM.
Step 1: Convert times to 24-hour format → Start: 9.5 hours, End: 14.25 hours.
Step 2: Subtract start from end → 14.25 − 9.5 = 4.75 hours.
Step 3: Convert hours to minutes → 4.75 × 60 = 285 minutes.
Solution: Duration = 4 hours 45 minutes (or 285 minutes)

Step-by-Step Example 2: Overnight Duration

Problem: Start time: 10:00 PM, End time: 2:30 AM.
Step 1: Convert to 24-hour format → Start: 22.0 hours, End: 2.5 hours (next day).
Step 2: Since end is less than start, add 24 → 2.5 + 24 = 26.5 hours.
Step 3: Subtract start → 26.5 − 22 = 4.5 hours.
Solution: Duration = 4 hours 30 minutes
