Calculating the days since April 20, 2025 is a straightforward process:
1. Identify the target date:
April 20, 2025
2. Identify the current date:
September 13, 2025
3. Convert both dates to millisecond timestamps and calculate the difference:
targetDate = 1,745,107,200,000 milliseconds
today = 1,757,766,876,263 milliseconds
difference = 12,659,676,263 milliseconds
4. Convert milliseconds to days:
12,659,676,263 milliseconds ÷ 86,400,000 milliseconds/day = 146 days
Therefore, there are 146 days since April 20, 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.
