- Your data never leaves your device
- Results are calculated instantly
- No internet connection is needed after the page loads
- Leap years are automatically accounted for (every 4 years, except centuries, except 400-year marks)
- Varying month lengths (28, 29, 30, or 31 days) are handled correctly
