One reminder on the day is too late for most things that are months away. How to space reminders out, turn the prep into dated tasks, and keep the date in view.
To remember something that's weeks or months away, set several reminders instead of one, spaced closer together as the date gets near: for example two months, one month, a week, and the day before. Then give each piece of preparation its own task with its own date. A single reminder on the day usually comes too late, because most of the work has to happen before the day.
Think of a friend's wedding in another city in March, a conference you signed up for, a deposit due in eight weeks, an exam, or tickets that go on sale on a set morning. You know about all of them well in advance. The problem is the long stretch in between, when nothing brings them up. By the time you think of it again, the cheap flights are gone or the deadline was yesterday.
A reminder fires once, at the time you set. If you can't act in that moment, because you're driving or at work or halfway through something else, you dismiss it and it's gone. For a task due today that's annoying. For something months away it's worse, because a single reminder set for the day itself tells you about the wedding on the morning of the wedding.
Things that are far away also need steps before the date: booking travel, asking for time off, buying a gift, paying a deposit, studying. Each of those has its own deadline, and each one is easy to forget because the main date still feels far off.
Pick lead times based on your longest preparation step, then add a few closer to the date. For a wedding in another city, that might be:
Most calendar apps let you do some of this on the event itself. In Google Calendar you can add more than one notification to an event, each with its own lead time. Apple Reminders gives each reminder one date and time, plus an optional early reminder, so for more lead times than that you'd make each step its own reminder. That's the better approach anyway, as the next section explains.
"Wedding" isn't something you can do. "Book the train to Leeds" is. The Getting Things Done method calls this the next action: the next physical step that moves something forward.
Work backwards from the date. Write down each step, give it a date that leaves you enough time, and put it in the same place as your other tasks. Now the far-off event shows up as small, doable tasks spread across the weeks before it, instead of one big date you only notice when it arrives.
Reminders cover the steps you thought of. A weekly look-ahead catches the ones you didn't. Pick a fixed time, like Sunday evening, and spend ten minutes scanning the next four to eight weeks of your calendar and task list. Ask what each coming date needs from you before it arrives, and add anything missing.
This is a lighter version of the weekly review from Getting Things Done. The point of it here is simple: once a week, every far-off date gets looked at again, so none of them sits untouched for two months.
Nudge is our app, and this is our blog. Nudge is a reminder app that keeps checking in until it's done, and it was built for exactly this problem: things you've agreed to or signed up for that slip out of your head before they're due.
You tell Nudge the date and the reminders you want in plain words, typed or spoken: "the wedding is on 14 March, remind me on 10 January to book travel, a month before to buy the gift, and the day before to pack." Nudge sets up each reminder you ask for, at the times you gave. You can ask for as many as you need.
The preparation steps work best as their own tasks with a deadline, like "book travel by 10 January". For a task with a deadline, Nudge also reminds you on its own as the date gets close, and more often the closer it gets. With the default Steady setting that's up to four days: about 6 days before, 3 days before, the day before and on the day, fitted around your quiet hours and your other reminders. Set the task to Persistent and it starts 14 days out. Before that last stretch, and for the event day itself, Nudge reminds you when you've asked it to, which is why the lead times above are worth setting.
If the date is a deadline, like a deposit or a form, and it passes without the task marked done, Nudge keeps checking back instead of letting it drop. On the Free plan that's the next day, day 3 and day 7. On Pro, Nudge plans the follow-ups itself for up to 14 days. On an iPhone with iOS 26 or later, you can make the most important reminder a real alarm that rings even when the phone is on silent.
On Pro, you can also snap a photo of a ticket or an invitation in chat. Nudge reads it and shows what it found as a checklist, and you pick what becomes a task. Tasks, reminders, follow-ups and alarms are on the Free plan.
Nudge reads your calendar and learns your patterns, then holds each reminder until a moment you can use.
