Time Percentage Calculator
Calculate what percentage of time has passed
In any unit: hours, days, weeks, etc.
Use the same unit as elapsed time
How to Use This Calculator
Enter Elapsed Time
Type how much time has already passed (e.g., 15 days, 6 hours, 4 weeks).
Enter Total Time
Type the total duration in the same units (e.g., 30 days, 8 hours, 6 weeks).

Formula
Time Percentage = (Elapsed Time / Total Time) × 100
Example 1: Project deadline - 18 days passed of 30 total
Percentage = (18 / 30) × 100 = 60%
60% of time has elapsed, 12 days (40%) remaining
Example 2: Work day - 6 hours worked of 8 hour day
Percentage = (6 / 8) × 100 = 75%
75% of the workday is done, 2 hours left
Example 3: Semester - 10 weeks completed of 16 weeks
Percentage = (10 / 16) × 100 = 62.5%
Over halfway through the semester

- 0-25%: Early stage - plenty of time remaining
- 25-50%: Making progress - over a quarter done
- 50-75%: Past halfway - approaching deadline
- 75-90%: Critical phase - limited time left
- 90-100%: Final push - deadline approaching fast
Real-World Applications
Project Deadline: A 60-day project is 45 days in. At 75% complete, you have 15 days (25%) remaining to finish. This helps assess if you are on track.
Academic Semester: 8 weeks into a 16-week semester means you are 50% through. Perfect time to evaluate progress and plan remaining coursework.
Work Shift: 5 hours into an 8-hour shift is 62.5% complete. You can plan breaks and tasks for the remaining 37.5% of the day.
Tips for Time Management
- Check progress regularly to stay on track
- Use consistent time units for accuracy
- Plan buffer time for unexpected delays
- Adjust pace when reaching 75% mark
- Set milestone checkpoints at 25%, 50%, and 75%
- Use remaining time to prioritize tasks
Frequently Asked Questions
Can I use different time units?
Yes, but both values must use the same unit. You can use hours, days, weeks, months, or any consistent time measurement.
What if elapsed time is greater than total time?
The calculator will show over 100%, indicating you have exceeded the deadline or planned duration.
How do I convert between time units?
Use consistent units. For example: 1 day = 24 hours, 1 week = 7 days, 1 month ≈ 30 days. Convert before entering values.
Can I use this for countdowns?
Yes! Enter time passed since a start date and total time until your target date to see countdown progress.
Is this useful for tracking multiple deadlines?
Absolutely! Calculate each deadline separately to prioritize your time across multiple projects or tasks.
