Semester countdown calculator
Count down to the end of a semester. See weeks left, days left, percent elapsed, and percent remaining for school or university terms.
How the semester countdown works
Enter the day the semester starts and the day it ends. The calculator measures the whole span, the time that has passed and the time that is left. It shows the days left, the whole weeks left, and the percentage of the semester that has elapsed. The end date counts as a full day, so on the last day you still have time left until midnight.
The percentage is based on calendar time. It includes weekends and breaks, because it measures how far through the semester you are, not how many class days remain. To count class days, use the school days calculator.
Typical semester lengths
| Length | Weeks | Days |
|---|---|---|
| Short term | 10 | 70 |
| Common semester | 15 | 105 |
| Long semester | 16 | 112 |
| Quarter system term | 10 to 11 | 70 to 77 |
Real calendars differ by school and country. Always enter your institution’s official dates.
