After further discussion and study, Miller briefly adopted a new date—April 18, 1844—one based on the Karaite Jewish calendar (as opposed to the Rabbinic calendar). Like the previous date, April 18 passed without Christ's return. In the "Advent Herald" of April 24, Joshua Himes wrote that all the "expected and published time" had passed and admitted that they had been "mistaken in the precise time of the termination of the prophetic period". Josiah Litch surmised that the Adventists were probably "only in error relative to the event which marked its close". Miller published a letter "To Second Advent Believers," writing, "I confess my error, and acknowledge my disappointment; yet I still believe that the day of the Lord is near, even at the door."
