Calculating the days since January 20, 2025 is a straightforward process:
1. Identify the target date:
January 20, 2025
2. Identify the current date:
August 6, 2025
3. Convert both dates to millisecond timestamps and calculate the difference:
targetDate = 1,737,331,200,000 milliseconds
today = 1,754,459,709,122 milliseconds
difference = 17,128,509,122 milliseconds
4. Convert milliseconds to days:
17,128,509,122 milliseconds ÷ 86,400,000 milliseconds/day = 198 days
Therefore, there are 198 days since January 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.
