Followers of the Baháʼí Faith also recognize the Day-Year Principle and use it in understanding prophecy from the Bible. In the book, "Some Answered Questions", `Abdu'l-Bahá outlines a similar calculation for the 2300-year prophecy as given in the Christian section above. By applying the day-year principle, he demonstrates that the fulfillment of the vision of Daniel occurred in the year 1844, the year of the Báb's declaration in Persia i.e. the starting date of the Baháʼí Faith. This is the same year that the Millerites predicted for the return of Christ, and Baháʼís believe that William Miller's methodologies were indeed sound.
