The Dry January challenge is simple to explain: no alcohol from January 1 to 31. For Dry January 2027 that's a Friday start and a Sunday finish, 31 days in total. Simple to explain is not the same as easy to do, and the people who make it to February are usually the ones who didn't try it alone.
This guide covers where Dry January comes from, how to do it with friends, practical tips for the weeks that get hard, and a 31-day tracker you can copy. No lectures. Whether you're doing it for your sleep, your wallet or just to see if you can, it all counts.
What Dry January is (and who runs it)
Dry January is a campaign run by Alcohol Change UK, a UK charity. It started in 2013 with about 4,000 people, and has since spread far beyond the UK, with plenty of people joining in without ever signing up officially.
The charity has worked with Dr Richard de Visser at the University of Sussex to study participants. Its first study found that six months after the campaign, seven in ten people were still drinking less riskily than before. That matters, because the point isn't really 31 days without a drink. It's what you learn about your own habits along the way.
Before you start: if you drink heavily every day, or get shaky, sweaty or anxious when you go without, stopping suddenly can be dangerous. Talk to your doctor before you begin. They can help you cut down safely, and there is no shame in doing it with medical support. Alcohol Change UK's site also lists where to get help.
Why do Dry January with friends
Most Dry January challenges don't end with a decision. They end on a Thursday night when someone says "just one" and nobody else in the room is doing it. That's the whole problem, and a friend fixes it.
- You have someone to order the lime and soda with. Social pressure works both ways. When two of you are doing it, saying no becomes the normal thing.
- Someone notices. A private goal is easy to quietly renegotiate. A shared one isn't.
- It's more fun. Comparing mocktails, sending each other "day 12 and I slept like a baby" messages, planning a February celebration together.
There's research behind the idea that doing things together helps you stick with them. In a 1999 weight-loss study by Wing and Jeffery, 95% of people who signed up with friends completed the program, compared with 76% of those who signed up alone. Different goal, same mechanism: someone else is in it with you.
How to set it up with a friend or group
- Ask before New Year. December is the month to pick your partner. Someone you see or message most days is ideal: a partner, a sibling, a housemate, a coworker. In Daily Pact you can start the pact and invite them by name, so they get their own link with a seat held for them. If they still haven't joined by New Year's Eve, send a nudge.
- Agree what counts. Is alcohol-free beer fine? (Most people say yes. Some prefer to skip it for the month.) Decide together on day one so nobody argues about it in week three.
- Agree what a slip means. This is the most important rule. If one of you has a drink on day 14, the challenge isn't over. You mark the day, you start again tomorrow. One slip is not a reason to stop.
- Check in every evening. One message, or one tap in an app. "Dry today" is enough. In Daily Pact it really is one tap, and your friend gets a notification the moment you check in, so neither of you has to remember to ask.
- Plan the finish. Book something for the first weekend in February: a dinner, a hike, a day out. A finish line you're looking forward to helps in week three.

Dry January tips for the hard weeks
Week 1 (Jan 1 to 3): The easiest days for most people. Many are recovering from New Year's Eve anyway. Use them to stock the fridge with drinks you actually like.
Week 2 (Jan 4 to 10): Back to work, back to routine, and the novelty wears off. This is the week that contains Quitter's Day, the second Friday in January (January 8 in 2027), when motivation for new habits often dips. Make a plan for Friday evening in advance. This is where a pact partner earns their place: by Friday night they can see whether you've checked in today, and a nudge from them at 9pm is much harder to ignore than a promise you made to yourself on January 1.
Week 3 (Jan 11 to 17): Social plans start up again. Tell people you're doing Dry January before you arrive, not at the bar. Most will be fine with it, and some will be doing it too.
Week 4 (Jan 18 to 24): By now you have three weeks of evidence about how a month off feels for you. This is a good week to write down what you've noticed, so you remember it in February.
Week 5 (Jan 25 to 31): The finish line is in sight. Payday weekend can be a trap. Plan the last Saturday as carefully as you planned the first.
A few more practical tips:
- Replace the ritual, not just the drink. If 6pm is "wine o'clock", have something else at 6pm: sparkling water with bitters, a nice tea, a walk.
- Have your order ready. Decide your go-to drink before you get to the pub so you're not standing at the bar improvising.
- Track the money. Write down what you'd normally spend. The total at the end of January is often the most motivating number of the month.
- Be kind to yourself. Cravings pass. Bad days pass. If you need to leave a party early, that's a perfectly good strategy.
Alcohol-free ideas for January evenings
Dry January goes better when the month is full of good things, not just missing one thing.
- A weekly mocktail night where you each try a new recipe
- A Friday-night film club with proper snacks
- Morning plans you'd normally skip: a Saturday park run, a swim, a long brunch
- A board game or quiz night with the other people doing it
- Dinner out at a place known for its food, not its bar
- A new hobby for the month: climbing, pottery, a cooking class

At the end of each week, compare notes with your friend: how many dry days, how you slept, how much you saved.
Is there a Dry January app?
Yes. The official Dry January application is Try Dry, from Alcohol Change UK. It's free and tracks dry days, units, calories and money saved. If you're doing it on your own, that's a great place to start.
If you're doing it with a friend or a group, you'll want something that shows each other's check-ins. That's what we built Daily Pact for: you start a pact with one friend or a small group, everyone checks in with one tap, and you all see who stayed dry today. Friends can nudge and cheer each other on, and the streak grows together. You can also set a daily reminder for the time you'd normally pour a drink, which is usually the moment that needs a plan. Plenty of people use both: Try Dry for the numbers, Daily Pact for the people.

What happens after January
Thirty-one days is enough to learn a lot about your habits, but not always enough to change them for good. Habit research by Lally and colleagues (2010) found that a new daily behavior took a median of 66 days to feel automatic. If you want to keep drinking less in February, keep checking in. Some people move to "dry weekdays", others just keep tracking.
And if Dry January is one of several things you want to change in 2027, our hub on goals for the new year helps you put it in context.
FAQ
When is Dry January 2027? From Friday January 1 to Sunday January 31, 2027. That's 31 days.
What if I slip during Dry January? Keep going. A drink on one day doesn't cancel the days before it. Mark it, talk to your friend about what made it hard, and plan around it for next time.
Does alcohol-free beer count? That's up to you and your group. Most people include it, but if the taste is a trigger for you, skip it. Agree on it before January 1.
Is Dry January safe for everyone? For most people, yes. But if you are physically dependent on alcohol, stopping suddenly can be dangerous. Speak to your doctor first so you can cut down safely.
What's the best Dry January app? Try Dry, the free official app from Alcohol Change UK, is the best for tracking units and money on your own. To do it with friends and see each other's check-ins, a shared habit tracker like Daily Pact works well.
