A Foundational Truth About God’s Appointed Calendar

Many believers assume that a day begins at sunrise—but Scripture reveals a different pattern.

From the very beginning in Genesis, the order is clear: evening comes before morning, establishing the structure of a full day.

This is not a minor detail. It directly affects how we understand and observe:

  • The weekly Sabbath
  • The biblical feast days (moedim)
  • The timing of key prophetic events

Throughout Scripture, this pattern is confirmed repeatedly—from the creation account, to God’s explicit instructions in the Law, to the practices seen in the time of Yeshua.
