FAQs

Why include a shadow-based method when a water-clock exists?

Redundancy and verification: shadow measurement works in the field without instruments and can cross-check clock time to deter tampering.

What is the administrative intent of defining ‘midday’ as shadowless?

It provides an observable, dispute-resistant reference point for deadlines, court sessions, market regulation, and duty changes.
