Days per week starts at 5 and takes whole numbers from 1 to 7. The optional Program hours per academic credit adds an estimate of credits earned. Every result also lists the total hours, the hours per week, the duration in weeks and approximate months, and the same hours as 8-hour workdays.

Days to complete your hours
h is the hours worked per day, and the answer is rounded up to whole workdays. A 200 hour internship at 8 hours a day takes 25 workdays, which is 5 weeks at 5 days a week. A 400 hour internship takes 50 workdays, or 10 weeks.
| Internship hours | 8 hours a day | 6 hours a day | 4 hours a day |
|---|---|---|---|
| 100 | 13 days | 17 days | 25 days |
| 120 | 15 days | 20 days | 30 days |
| 150 | 19 days | 25 days | 38 days |
| 200 | 25 days | 34 days | 50 days |
| 240 | 30 days | 40 days | 60 days |
| 300 | 38 days | 50 days | 75 days |
| 400 | 50 days | 67 days | 100 days |
| 480 | 60 days | 80 days | 120 days |
| 500 | 63 days | 84 days | 125 days |
| 600 | 75 days | 100 days | 150 days |
Total hours from a weekly schedule
The main formula applies directly: 20 hours a week for 10 weeks is 200 hours.
Total hours from a daily schedule
d is the days per week. 6 hours a day, 4 days a week for 12 weeks is 288 hours.
Required hours per week
300 hours in 12 weeks needs 25 hours a week. A result above 168 hours, the length of a week, is not accepted.
Weeks from a weekly schedule
300 hours at 20 hours a week takes 15 weeks, about 3.46 months at 52 weeks to 12 months.
Academic credits
Estimated credits are the total hours divided by the hours per credit entered. That figure is set by each school or program, so there is no standard value to fall back on.
Limits of This Estimate
- Holidays, absences and breaks are not counted, and no calendar end date is worked out.
- A part week counts as the same share of a normal week. The real finish depends on which days are worked.
- Which hours count, and how many credits they earn, is decided by the program. Confirm both with an academic advisor.
