Time-to-Defense Countdown
The days, weeks, months, and Mon–Fri working days between now and your defense or viva — so you can plan the run-up around the time you really have.
Time to defense
Choose your defense date to see the countdown.
The working-day count is a plain Mon–Fri tally — it doesn’t know your holidays, teaching load, or public holidays, so treat it as an upper bound on genuine prep time.
Prep time you can actually see
The stretch before a defense is deceptively short. “A couple of months away” can hide the fact that only thirty or so working days stand between you and the examiners. This countdown makes the real number visible — calendar days for the big picture, working days for the honest planning figure.
Use it to lay out a preparation schedule: when to finish the slides, when to book a mock defense, when to step back and rest before the day itself.
Frequently Asked Questions
How does the countdown work?
Pick your defense or viva date and, if you want, a start date to count from (it defaults to today). The tool returns the total calendar days between the two, the same span expressed as whole weeks plus leftover days, an approximate number of months, and the count of Monday-to-Friday working days in the interval.
Why show working days as well as calendar days?
Because preparation happens on working days, not weekends. The raw calendar count can feel reassuringly large while the number of genuine prep days is much smaller. Seeing the Mon–Fri figure gives a more realistic sense of how much time you actually have to rehearse the talk, re-read the thesis, and prepare for questions.
Does the working-day count include holidays?
No. It's a plain Monday-to-Friday tally that doesn't know your public holidays, teaching load, leave, or the days you'll lose to other commitments. Treat it as an upper bound on available preparation time and subtract your own known interruptions.
What's the difference between a defense and a viva?
They're regional names for the same milestone — the oral examination where you defend your dissertation to a committee or examiners. 'Defense' is common in North America, 'viva' (short for viva voce) in the UK and elsewhere. The countdown works the same whichever term your program uses.
How should I use the countdown while preparing?
Check it at the start of your prep to block out a realistic schedule, then again at milestones — slides done, mock defense booked, thesis re-read — to see whether you're on track. Watching the working-day number shrink is a useful nudge to keep momentum without leaving everything to the final week.
