Total Weeks = Total Days ÷ 7
Remaining Days = Total Days mod 7The difference between two dates is calculated in milliseconds and converted to days by dividing by the number of milliseconds in a day (86,400,000 = 1000ms × 60s × 60m × 24h). Weeks and remaining days provide a more human-readable breakdown.
