How the count works
There are two ways to count. “Days since” is the plain difference between the two dates, so the day after you met is 1. Many couples — especially in Korea, Japan and China — count the first day itself as day 1, so they are always one ahead. Both are shown above.
Milestones use the second way: day 100 falls 99 days after the day you met. Anniversaries fall on the same date each year.
Questions
How do I calculate how many days we have been together?
Subtract your start date from today’s date. For example, from 14 February 2024 to 14 February 2025 is 366 days, because 2024 was a leap year.
When is our 100th day?
If the first day counts as day 1, the 100th day is 99 days after it. Starting on 1 March, day 100 is 8 June.
Can the count stay on our phones?
Yes. TT, a free shared calendar for couples, shows how many days you have been together and puts every 100 days and anniversary on the calendar for both of you.
