Calculating the days since May 12, 2025 is a straightforward process:
1. Identify the target date:
May 12, 2025
2. Identify the current date:
September 13, 2025
3. Convert both dates to millisecond timestamps and calculate the difference:
targetDate = 1,747,008,000,000 milliseconds
today = 1,757,766,116,859 milliseconds
difference = 10,758,116,859 milliseconds
4. Convert milliseconds to days:
10,758,116,859 milliseconds ÷ 86,400,000 milliseconds/day = 124 days
Therefore, there are 124 days since May 12, 2025.
Note: Our calculation method sets both the target date and current date to 00:00:00 (midnight) of their respective days to ensure we're counting complete days.
