The core calculation converts dates to timestamps and calculates the difference:
This formula accounts for leap years and varying month lengths to ensure accuracy.
Our date calculator uses JavaScript Date objects. First, it captures your selected dates. Then, it calculates the exact millisecond difference.
Next, it converts milliseconds to days. This is the foundation. Also, it accounts for leap years.
Moreover, it calculates weeks by dividing days. Months are calculated using average lengths. Years use the 365.25-day formula.
Furthermore, it handles time zones correctly. All calculations are precise. Therefore, results are reliable.
Finally, it displays all time units. You get a complete breakdown. Try it above!

A date calculator measures time between two calendar dates. It shows days, weeks, months, and years. This tool is essential for planning events and tracking durations. Also, it helps calculate ages and deadlines. Use it for personal or professional needs.
Our calculator is highly accurate. It accounts for leap years and varying month lengths. The algorithm uses precise time calculations. Therefore, results are reliable for most purposes. However, it uses average month lengths for simplicity.
Yes, absolutely! Our calculator works for any dates. You can calculate from past to present or future. The order doesn't matter. The result always shows the positive difference. It's perfect for historical research.
This calculator shows the full days between dates. For example, from Jan 1 to Jan 2 is 1 day. If you need inclusive counting, add one day. The tool displays the exact difference only.
Months have different lengths (28-31 days). Our calculator uses average month length (30.436875 days). This provides consistent results. For exact month counts, consider calendar months.
