How It Works
Understanding the Calculation
🔹 Days Until = target date − today (if target in future)
🔹 Days Since = today − target date (if target in past)
🔹 Weeks = floor(days / 7) | Months ≈ days / 30.44 | Hours = days × 24
🔹 Days Since = today − target date (if target in past)
🔹 Weeks = floor(days / 7) | Months ≈ days / 30.44 | Hours = days × 24
Planning Ahead
Use future dates to countdown to deadlines, events, or trips.
Looking Back
Past dates show how long ago something happened (anniversary, graduation).
Precision
Days are calculated based on UTC midnight difference to avoid timezone issues.
