Calculating the days since May 1, 2025 is a straightforward process:
1. Identify the target date:
May 1, 2025
2. Identify the current date:
September 29, 2025
3. Convert both dates to millisecond timestamps and calculate the difference:
targetDate = 1,746,057,600,000 milliseconds
today = 1,759,177,191,281 milliseconds
difference = 13,119,591,281 milliseconds
4. Convert milliseconds to days:
13,119,591,281 milliseconds ÷ 86,400,000 milliseconds/day = 151 days
Therefore, there are 151 days since May 1, 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.
