Multi-Factor Synthesis

Solving problems by decomposing large year ranges into centuries, decades, and remaining individual years.

Essential Formulation Tips

  • Always break large time spans into smaller, manageable chunks (centuries first, then years).
  • Re-verify leap year counts—they are the most common source of error.

Shortcut Execution Techniques

  • Use the reference: Jan 1, 1901, was a Tuesday. Any date can be calculated relative to this or other known anchors.
