Calculating the days since July 21, 2025 is a straightforward process:
1. Identify the target date:
July 21, 2025
2. Identify the current date:
August 2, 2025
3. Convert both dates to millisecond timestamps and calculate the difference:
targetDate = 1,753,056,000,000 milliseconds
today = 1,754,139,879,538 milliseconds
difference = 1,083,879,538 milliseconds
4. Convert milliseconds to days:
1,083,879,538 milliseconds ÷ 86,400,000 milliseconds/day = 12 days
Therefore, there are 12 days since July 21, 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.
