A thousand days is a lovely number to celebrate. It is long enough to mean something, about two years and nine months, and it rarely lands on a date anyone else expects, so it feels like a private occasion. Couples in South Korea have long celebrated day counts such as 100 and 1,000 days, and the idea has spread because it is simple and fun. This guide shows you how to find your date, explains what makes the milestone special and gives 20 ideas for marking it, whether you are in the same city or on different continents.
When is 1,000 days together?
Count your start date as day 1, then add 999 days, or simply use a calculator so you do not have to think about leap years. As a rough guide, 1,000 days is 142 weeks and 6 days, or a little under two years and nine months. If you started dating on 1 March 2024, for example, day 1,000 falls on 25 November 2026 when the start date counts as day 1.
Some couples count the start date as day 0 instead, which moves the milestone one day later. Neither is wrong; just pick one and stick to it, so your 100-day, 500-day and 1,000-day celebrations line up.
Which start date to use is a bigger question than which counting rule. Some couples count from the first date, others from the day they became official or the first time they met in person. If you have never agreed, the 1,000-day mark is a sweet excuse to decide together.
| Milestone | Roughly |
|---|---|
| 100 days | 3 months and 1 week |
| 365 days | 1 year |
| 500 days | 1 year and 4.5 months |
| 730 days | 2 years |
| 1,000 days | 2 years and 9 months |
| 2,000 days | 5 years and 5 months |
Why 1,000 days is worth celebrating
By day 1,000 most couples have been through a full set of seasons more than twice: birthdays, holidays, at least one hard patch and probably a few big decisions. It is past the honeymoon stage and often before the next big step, which makes it a natural point to look back.
It is also a milestone you choose to notice. Anniversaries arrive on the calendar for everyone; a day count is something you track because you care. For long-distance couples in particular, counting up rather than only counting down to the next visit is a nice change in perspective.
Ideas for celebrating at home
You do not need a trip to make it feel special. These ideas work in an evening.
1. A 1,000-day timeline
1–2 hours · Free
Pick one photo or memory from each season you have had together and lay them out in order. Talk about what you remember from each. Our relationship timeline maker turns it into a shareable image.
2. Recreate your first date
An evening
Same food, same drink, same film or as close as you can get. Compare how nervous you were then with how comfortable you are now.
3. Write a letter to your day-2,000 selves
30 minutes
Each write a short letter about where you hope to be in another 1,000 days, seal them and agree to open them on day 2,000.
4. A thousand-word letter
1 hour
Write your partner exactly a thousand words: memories, thank-yous, things you have never said. The number gives you a goal and stops you from overthinking.

An evening
A small tasting menu from your first date, first trip and first meal you cooked together.

7. Your own awards ceremony
45 minutes · Free
Make up categories such as best trip, funniest argument and best gift, and hand out the awards over dinner.
Ideas for a day out or a trip
If you live close enough, or day 1,000 lands on a visit, take the celebration outside.
8. Go back to where you met
Half a day
Visit the café, campus, park or station where it started. Take a photo in the same spot.
9. Book something neither of you has tried
Varies
A pottery class, a climbing wall or a cooking workshop. The first 1,000 days were full of firsts; start the next 1,000 with one more.
10. A short trip to a new place
A weekend
Somewhere small and new, close enough not to need much planning. New places make new memories quickly.
11. A sunrise or sunset walk
1 hour · Free
Simple and quiet. Bring a flask and talk about your favourite moment of each year.
12. A photo booth strip
15 minutes · Small spend
Find a photo booth and make it the first entry for your next 1,000 days.
Ideas if you are apart on day 1,000
Long-distance couples often reach day 1,000 on a video call, and it can still feel like a proper occasion with a little planning.
13. A synchronised dinner
1–2 hours
Cook or order the same meal and eat together on camera. Our virtual dinner date guide explains how to keep it relaxed.
14. A memory quiz
30 minutes · Free
Write ten questions about your first 1,000 days and quiz each other. Who remembers the first film you watched together?

Something small and specific: a printed photo, their favourite snack from your city, a handwritten note.
17. A shared drawing
20 minutes
Draw a picture of your next 1,000 days together on one canvas, such as the home you want, the trip you dream of or the pet you have argued about. MileHeart’s Live Drawing lets you draw it together in real time.
18. Plan the next visit
45 minutes
Spend part of the call booking or planning the next time you will see each other. Celebrating with a date on the calendar is the best gift for many couples.
Simple 1,000-day gift ideas
Small, personal gifts tend to land better than expensive ones on day counts, because the milestone itself is the point.
19. A ‘1,000 reasons’ jar
A few evenings
A thousand is a lot, so be honest: a jar of 100 reasons, with a note saying the other 900 are coming in person.
20. A framed day-1 and day-1,000 photo
Small spend
Your earliest photo together next to one taken on the day. It is simple and surprisingly moving.
