Practical Example

Let’s imagine a real-life scenario:

• Original Scheduled Time: 8:00 AM (a train’s departure time)
• Actual/Expected Time: 8:45 AM
• Reason for Delay: Track maintenance

After entering the details and clicking calculate, the tool will show:

• Total Delay: 0h 45m
• Status: Delayed
• Reason: Track maintenance

This provides clear, easy-to-understand information that can be shared with team members, colleagues, or anyone waiting on the event.

Now imagine the actual time was 7:50 AM instead. The tool would show:

• Total Delay: -0h 10m
• Status: Ahead of Schedule

This feature ensures you can also track early starts, not just delays.
