⚙️ How the Time Calculator Works

The Time Calculator takes a reference date and time, a time unit (like days or months), an amount, and a direction (ago or from now). It then computes a new calculated date and displays detailed insights such as:

  • Calculated Date and Time (formatted for clarity)
  • Day of the Week
  • Relative Time (e.g., 3 days from now)
  • Unix Timestamp
  • Time Difference in Minutes, Hours, Days, and Weeks

All computations happen instantly in your browser -- no external APIs or backend calls -- ensuring privacy and blazing-fast results.
