Semester Countdown
About This Calculator
The semester countdown shows how many days are left until the end of term. Enter your semester's start and end dates and it leads with the days remaining, then fills in the weeks left and how much of the term you have already completed.
The end of a semester is the deadline everything else points at — final assignments, exams, projects, and the break that follows. Watching the number of days tick down is a simple, motivating way to pace the run-in: it tells you how many weekends are left for revision, how far apart to space the work still to do, and when to ease off. Because it also shows the percentage completed, you can see at a glance whether you are past the halfway mark.
The countdown counts inclusively to the last day of term and updates to today's date each time you open the page. Before term begins it counts down to the first day instead, so the same page works whether the semester is coming up or already underway; once term ends, it shows that the semester is over.
Everything runs privately in your browser in a timezone-safe way, so the figure is consistent wherever you are. To use it, enter the term start and end dates and read the days left at the top, with the weeks remaining and progress just below.
If you would rather lead with the semester's overall length in weeks, the academic semester calculator is framed that way; to count down to a single fixed date such as an exam, the days until date calculator does that, and the week number calculator gives the ISO week for any date.
How It Works
- Enter the term start date.
- Enter the term end date.
- Click “Show semester progress”.
- See the length in weeks, how far along you are, and days left.
Formula & Methodology
The result is worked out as follows:
Length = end − start + 1 day; progress = days elapsed ÷ total; weeks = ⌊total ÷ 7⌋
Days left counts from today to the last day of term (inclusive of that final day). The term's total length is the end date minus the start date plus one day; progress is days elapsed ÷ total days. Before term starts the page counts down to the first day instead.
Worked Examples
For Today is week 10 of a 14-week term, the result is About 4 weeks left.
For Term ends 1 May 2026, today 1 Apr 2026, the result is 30 days left.
For Today is after the last day of term, the result is Shows the semester has ended.
Frequently Asked Questions
How many days are left in the semester?
Enter your term start and end dates and the countdown shows the exact number of days remaining until the last day of term, updated to today's date.
