Our calculator is 100% accurate, calculating the exact number of days, weeks, months, and years between your start date and today. It accounts for leap years and varying month lengths. ### What milestones does it track? The calculator tracks popular relationship milestones including 100 days, 500 days, 1000 days, and yearly anniversaries up to 10 years. It shows you which milestones you've passed and which are coming up. ### Can I use this for any type of relationship? Yes! Whether it's a romantic relationship, friendship anniversary, or any other meaningful date, this calculator works for tracking any duration between two dates. ### How are the 'Shared Meals' calculated? We estimate approximately 3 meals per day together (breakfast, lunch, dinner) multiplied by your total days. This is just a fun estimate and may vary based on your actual habits. ### Is my relationship data stored? No, all calculations happen in your browser. We don't store any personal information or dates you enter. Your privacy is completely protected. ### What start date should I use? Use whichever date feels most meaningful to you and your partner. Common choices include the first date, the day you became exclusive, or the day you said 'I love you.' The important thing is that both partners agree on the date. ### Can I calculate how long a past relationship lasted? Yes. Change the end date from today to the date the relationship ended. The calculator will show the exact duration between any two dates, not just from a start date to today. ### Why do couples celebrate 100-day and 1000-day milestones? The 100-day milestone originated in Korean dating culture and has become popular worldwide as an early relationship celebration. The 1000-day mark, roughly 2 years and 9 months, represents a significant commitment and is celebrated with gifts or special outings in many cultures. ### Does it work for wedding anniversaries too? Absolutely. Enter your wedding date as the start date to see how long you have been married. The milestone tracker and fun facts work the same way, giving you a detailed view of your marriage duration. ### Can I share the results with my partner?
