No offense to anyone, but I don't put any faith in what the Baha'i are claiming on that. The Bible has a good track record on Jesus, etc. He came right on time - as prophesied - the first time.
By the way, the math that was used to calculate the first coming of Christ was accurate, and
the same math was use to calculate the second coming of Christ.
“Now we must prove from the Holy Books that these two Manifestations have come, and we must divine the meaning of the words of the Prophets, for we wish for proofs drawn from the Holy Books.
A few days ago, at table, we put forth rational proofs establishing the truth of these two Manifestations.
To conclude: in the Book of Daniel, from the rebuilding of Jerusalem to the martyrdom of Christ, seventy weeks are appointed; for by the martyrdom of Christ the sacrifice is accomplished and the altar destroyed.
4 This is a prophecy of the manifestation of Christ. These seventy weeks begin with the restoration and the rebuilding of Jerusalem, concerning which four edicts were issued by three kings.
The first was issued by Cyrus in the year 536 B.C.; this is recorded in the first chapter of the Book of Ezra. The second edict, with reference to the rebuilding of Jerusalem, is that of Darius of Persia in the year 519 B.C.; this is recorded in the sixth chapter of Ezra. The third is that of Artaxerxes in the seventh year of his reign—that is, in 457 B.C.; this is recorded in the seventh chapter of Ezra. The fourth is that of Artaxerxes in the year 444 B.C.; this is recorded in the second chapter of Nehemiah.
But Daniel refers especially to the third edict which was issued in the year 457 B.C. Seventy weeks make four hundred and ninety days. Each day, according to the text of the Holy Book, is a year. For in the Bible it is said: “The day of the Lord is one year.”
5 Therefore, four hundred and ninety days are four hundred and ninety years. The third edict of Artaxerxes was issued four hundred and fifty-seven years before the birth of Christ, and Christ when He was martyred and ascended was thirty-three years of age. When you add thirty-three to four hundred and fifty-seven, the result is four hundred and ninety, which is the time announced by Daniel for the manifestation of Christ.
But in the twenty-fifth verse of the ninth chapter of the Book of Daniel this is expressed in another manner, as seven weeks and sixty-two weeks; and apparently this differs from the first saying. Many have remained perplexed at these differences, trying to reconcile these two statements. How can seventy weeks be right in one place, and sixty-two weeks and seven weeks in another? These two sayings do not accord.
But Daniel mentions two dates. One of these dates begins with the command of Artaxerxes to Ezra to rebuild Jerusalem: this is the seventy weeks which came to an end with the ascension of Christ, when by His martyrdom the sacrifice and oblation ceased.
The second period, which is found in the twenty-sixth verse, means that after the termination of the rebuilding of Jerusalem until the ascension of Christ, there will be sixty-two weeks: the seven weeks are the duration of the rebuilding of Jerusalem, which took forty-nine years. When you add these seven weeks to the sixty-two weeks, it makes sixty-nine weeks, and in the last week (69–70) the ascension of Christ took place. These seventy weeks are thus completed, and there is no contradiction.
Now that the manifestation of Christ has been proved by the prophecies of Daniel, let us prove the manifestations of Bahá’u’lláh and of the Báb. Up to the present we have only mentioned rational proofs; now we shall speak of traditional proofs.
In the eighth chapter of the Book of Daniel, verse thirteen, it is said: “Then I heard one saint speaking, and another saint said unto that certain saint which spake, How long shall be the vision concerning the daily sacrifice, and the transgression of desolation, to give both the sanctuary and the host to be trodden under foot?” Then he answered (v. 14): “Unto two thousand and three hundred days; then shall the sanctuary be cleansed”; (v. 17) “But he said unto me … at the time of the end shall be the vision.” That is to say, how long will this misfortune, this ruin, this abasement and degradation last? meaning, when will be the dawn of the Manifestation? Then he answered, “Two thousand and three hundred days; then shall the sanctuary be cleansed.” Briefly, the purport of this passage is that he appoints two thousand three hundred years, for in the text of the Bible each day is a year. Then from the date of the issuing of the edict of Artaxerxes to rebuild Jerusalem until the day of the birth of Christ there are 456 years, and from the birth of Christ until the day of the manifestation of the Báb there are 1844 years. When you add 456 years to this number it makes 2300 years. That is to say, the fulfillment of the vision of Daniel took place in the year A.D. 1844, and this is the year of the Báb’s manifestation according to the actual text of the Book of Daniel. Consider how clearly he determines the year of manifestation; there could be no clearer prophecy for a manifestation than this.
In Matthew, chapter 24, verse 3, Christ clearly says that what Daniel meant by this prophecy was the date of the manifestation, and this is the verse: “As He sat upon the mount of Olives, the disciples came unto Him privately, saying, Tell us, when shall these things be? and what shall be the sign of Thy coming, and of the end of the world?” One of the explanations He gave them in reply was this (v. 15): “When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand).” In this answer He referred them to the eighth chapter of the Book of Daniel, saying that everyone who reads it will understand that it is this time that is spoken of. Consider how clearly the manifestation of the Báb is spoken of in the Old Testament and in the Gospel.
To conclude, let us now explain the date of the manifestation of Bahá’u’lláh from the Bible. The date of Bahá’u’lláh is calculated according to lunar years from the mission and the Hejira of Muḥammad; for in the religion of Muḥammad the lunar year is in use, as also it is the lunar year which is employed concerning all commands of worship.
In Daniel, chapter 12, verse 6, it is said: “And one said to the man clothed in linen, which was upon the waters of the river, How long shall it be to the end of these wonders? And I heard the man clothed in linen, which was upon the waters of the river, when he held up his right hand and his left hand unto heaven, and sware by Him that liveth for ever that it shall be for a time, times, and a half; and that when He shall have accomplished to scatter the power of the holy people, all these things shall be finished.”

As I have already explained the signification of one day, it is not necessary to explain it further; but we will say briefly that each day of the Father counts as a year, and in each year there are twelve months. Thus three years and a half make forty-two months, and forty-two months are twelve hundred and sixty days. The Báb, the precursor of Bahá’u’lláh, appeared in the year 1260 from the Hejira of Muḥammad, by the reckoning of Islám.
Afterward, in verse 11, it is said: “And from the time that the daily sacrifice shall be taken away, and the abomination that maketh desolation be set up, there shall be a thousand two hundred and ninety days. Blessed is he that waiteth, and cometh to the thousand three hundred and five and thirty days.”

The beginning of this lunar reckoning is from the day of the proclamation of the prophethood of Muḥammad in the country of Ḥijáz; and that was three years after His mission, because in the beginning the prophethood of Muḥammad was kept secret, and no one knew it save
Khadíjah and Ibn Nawfal.
8 After three years it was announced. And Bahá’u’lláh, in the year 1290 from the proclamation of the mission of Muḥammad, caused His manifestation to be known.
