Calculating the days since September 4, 2025 is a straightforward process:
1. Identify the target date:
September 4, 2025
2. Identify the current date:
November 2, 2025
3. Convert both dates to millisecond timestamps and calculate the difference:
targetDate = 1,756,944,000,000 milliseconds
today = 1,762,068,922,530 milliseconds
difference = 5,124,922,530 milliseconds
4. Convert milliseconds to days:
5,124,922,530 milliseconds ÷ 86,400,000 milliseconds/day = 59 days
