Calculating the days until December 26, 2025 is a straightforward process:
1. Identify the target date:
December 26, 2025
2. Identify the current date:
July 30, 2025
3. Convert both dates to millisecond timestamps and calculate the difference:
targetDate = 1,766,707,200,000 milliseconds
today = 1,753,854,830,740 milliseconds
difference = 12,852,369,260 milliseconds
4. Convert milliseconds to days:
12,852,369,260 milliseconds ÷ 86,400,000 milliseconds/day = 149 days
Therefore, there are 149 days until December 26, 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.
