The days you don't work
Weekends aren't always Saturday and Sunday any more. A working week isn't always 5 days. Deadlinewatch lets you say which days are yours, then shows you every deadline that falls on one.

Your working week is probably not the one on the poster. The deadlines still arrive as though it were.
Work went global and went remote, and the 5-day Monday-to-Friday week went with it. You might take Fridays off and pick up Sundays. You might run 4 days one month and 6 the next. Your weekend might be Thursday and Friday. Your day might run 6 hours or 11, split around a school run and a client 8 time zones away. None of that is unusual now. Most software still assumes otherwise, and quietly hands you a Saturday deadline as though Saturday were free. A calendar marks the date and stops there, whatever the day means to you.
Deadlinewatch assumes nothing about your week. You tell it which days are yours. It shows you every deadline that falls outside them.
You set all 7 days
Tick the days you don’t work and you have your pattern. It runs from now on, because a pattern is a rule.
Then you layer real dates on top, in both directions. Mark a week off in October that your pattern calls working days. Or work a Saturday your pattern calls free, and say so, and Deadlinewatch treats that one Saturday as a working day. Both directions matter, because a real calendar goes both ways. You take days, and you give them back.
Mark a stretch and you get the stretch. Mark one day and you get one day. Nothing about it assumes a country, a season, or an industry.
The reconciliation
This is the part I would point at first.
Every deadline you carry falls into one of two categories, and you have always known which without ever writing it down. Either it lands on a day you will be working, or it lands on a day you won’t. The first kind takes care of itself. The second kind is where a week goes wrong, and it goes wrong quietly, because a Saturday deadline looks exactly like a Tuesday deadline on every list you have ever used. It is one more thing the shape of your week is holding that a list cannot show you.
Deadlinewatch puts that distinction on the screen. Open Add dates and there is a list of exactly the deadlines that fall on days you don’t work. Not a warning banner you dismiss. A short, standing list of the ones that need a decision from you.
And you can reach it from either side, which is the half most people miss. Add a deadline onto a day you don’t work and it appears. Mark a week off on top of deadlines you already had and the same deadlines appear, in the same list. Import a spreadsheet, generate a repeating series, drop a date by hand. All of it feeds one list. A tool that warned you one way and stayed quiet the other would be silent exactly half the time, and silence reads as good news.
You get 3 answers, and one of them is to do nothing.
Move the deadline. Keep it exactly where it is. Or keep it and say so, which clears the row and leaves the fact standing.
That middle answer is the one I care most about. Plenty of deadlines belong on a day you don’t work, and Deadlinewatch has no business suggesting otherwise. Something is due Sunday because Sunday is when it’s due. You will handle it Friday, or you will answer one email on your day off because that’s the week you’re having. Neither is a mistake. Software that treats every one of these as an error to fix is software that argues with you. Deadlinewatch states what is true and leaves the judgment to you, here as everywhere else.
Record a decision and the row leaves the list. The calendar keeps drawing it, because it is still true. What changed is that you have looked at it.
One detail earns its keep here. Your decision attaches to the date, not to the deadline. Move that deadline onto a different day off later and Deadlinewatch raises it again, because that is a new collision and you haven’t seen this one yet.
“Move to” only ever points backward
When Deadlinewatch offers to move something, it offers one destination. The working day before.
Never the working day after, and I want to be plain about why. Rolling a deadline forward past a closed day is a real rule for certain filings in certain places. It is flatly wrong for a great many contracts and submissions, where a date that falls on a Sunday is due on the Sunday and Monday is late. To offer that move, Deadlinewatch would have to know which of those you are holding. It doesn’t, and it isn’t a tool that works dates out from anybody’s rules.
Moving something earlier claims nothing at all. It is simply earlier. That is the only move on offer, and even that is a suggestion you click.
For the same reason, Deadlinewatch ships no holiday data. No built-in list, no country picker, no calendar file to import. A holiday list is a claim about your jurisdiction and your industry, and one wrong entry costs somebody a filing. You mark the days you don’t work. A day off means you said so, and nothing else.
The calendar tells you where it stops
Here is the smallest piece, and I think it matters most.
Your weekly pattern runs from now on. Individual dates run out. Mark August off, say nothing about the rest of the year, and by November Deadlinewatch has nothing to go on. An empty November and a clear November look identical from the outside, and every warning would go quiet in both.
The form says where your marked dates end. “Marked through 5 Aug 2026. Nothing after that.” One line, always visible. A tool that is quiet because there is nothing to report and a tool that is quiet because it doesn’t know are the same experience until the day they aren’t, and you should never have to guess which one you are looking at.
Mark your days. See what falls outside them, from either direction. Decide each one, including the ones you decide to leave. Deadlinewatch holds the calendar. You keep the judgment.
Common questions
Does Deadlinewatch move a deadline off a day I don’t work? No, never, in any circumstance. It shows you that the deadline falls on a day you marked off and offers to move it to the working day before, which you click or ignore. Leaving it where it is counts as an answer, and recording that decision clears it from the list.
Why won’t it move a deadline forward to the next working day? Rolling a date forward past a closed day is true for some filings and false for many contracts and submissions, and Deadlinewatch has no way of knowing which you are holding. Offering it would mean claiming a rule it doesn’t have. Moving something earlier claims nothing, so that is the only suggestion on offer.
Does it know about public holidays? No, and it won’t. Deadlinewatch ships no holiday data in any form, including calendar imports. A holiday list is a claim about your country and your industry, and one wrong entry costs somebody a date. You mark the days you don’t work, and a day off means you said so.
Can I set a working week that isn’t Monday to Friday? Yes. You pick which of the 7 days you don’t work. It starts on the weekend because that is the common case, not because it is assumed. Real dates layer on top in both directions, so you can take a Wednesday off and give a Saturday back when you’re working it.
What happens if I mark a week off and I already have deadlines in it? They appear in the reconciliation list immediately, each one named. It is the same list you would see had you added a deadline onto a day off instead. Both directions of the same collision arrive in one place.
