The days worth marking
100 days
In South Korea couples celebrate their 100th day (baegil) with a small gift or a dinner, and many keep going: 200 days, 300, then 1,000. They count the day they got together as day 1, so the 100th day comes 99 days after it. Tick the box above to count that way.
Monthiversaries
The same date every month, usually only in the first year, while every month still feels like news. Started on the 29th, 30th or 31st? A month too short for your date gets its last day instead, so 31 January leads to 28 February.
1,000 days
Two years and nine months, give or take, and a date almost nobody sees coming, which is the fun of it. The counter shows which day of the week it falls on, so you can plan the evening around it.
Anniversaries
The one everyone remembers, on the date you got together. If that was 29 February, this calculator puts it on 28 February in common years so it stays in February; some couples pick 1 March instead.
Make the day itself
A milestone lands better with something to open. These open on their phone with your photos and your words, and Midnight Countdown waits for the exact minute you pick.

How do you count how long you've been together?
Count the calendar days from the day you got together to today: the day itself is zero and the next day is one. This calculator counts from midnight on your date in your own time zone, and its months follow the calendar, so 31 January to the last day of February is one month.
Does the first day count?
It depends who's counting. Most calculators start at zero, so you reach 100 days a hundred days after you got together. Couples in South Korea count the first day as day 1, so their 100th day comes a day sooner. The box above switches between the two.
When is our 100-day anniversary?
A hundred days after the day you got together, or 99 days after it if you count the first day as day 1. Put your date in above to see the exact date and weekday, along with 200, 300, 500 and 1,000 days.
What is a monthiversary?
The same date every month, kept by couples who mark the months, usually in the first year. If you got together on the 29th, 30th or 31st, a month too short for that date gets its last day instead: start on 31 January and the first one is 28 February, or the 29th in a leap year.
We got together on 29 February. When is our anniversary?
On 29 February in leap years. In the other three this calculator puts it on 28 February, so it stays in February, though some couples prefer 1 March. Your day counts, like 100 and 1,000 days, don't change.
How long is 1,000 days?
Two years and 269 or 270 days, depending on whether a 29 February falls in between: close to two years and nine months. Put your date in above and it shows the exact day and its weekday.
Do you keep our date?
No. The date stays in your browser, which remembers it on this device so the counter is there next time. If you copy the link, the date goes into it, so whoever opens it sees your count too.
