How It Works
The formula is: Total Days = (Months × 30) + Additional Days. Each month is approximated as exactly 30 days, which keeps the calculation simple and consistent. Total weeks is the floor of total days divided by 7 (e.g., 90 days ÷ 7 = 12 weeks with 6 days remaining). Total hours is total days multiplied by 24. As a worked example: 3 months and 15 days = (3 × 30) + 15 = 90 + 15 = 105 days total. 105 ÷ 7 = 15 weeks exactly. 105 × 24 = 2,520 hours. For events where the exact calendar date matters (and the distinction between 28, 30, and 31-day months is important), the Countdown Calculator accepts specific year/month/day inputs for a precise count.
