Calculating the days since March 31, 2025 is a straightforward process:
1. Identify the target date:
March 31, 2025
2. Identify the current date:
October 29, 2025
3. Convert both dates to millisecond timestamps and calculate the difference:
targetDate = 1,743,379,200,000 milliseconds
today = 1,761,752,227,720 milliseconds
difference = 18,373,027,720 milliseconds
4. Convert milliseconds to days:
18,373,027,720 milliseconds ÷ 86,400,000 milliseconds/day = 212 days
Therefore, there are 212 days since March 31, 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.
