Both years are significant, but the nine years fulfills the Bible prophecies.
The Old Testament clearly prophesied Twin Holy messengers that will come in succession, one right after the other.
“Zechariah, speaking of the last days, prophesied of the twin holy souls who would appear, saying: “Then said he, These are the two anointed ones, that stand by the Lord of the whole earth.”(Zechariah 4:14). In addition to the two ‘woes’,
Revelation speaks of the ‘two olive trees’ and the ‘two candlesticks’. Malachi, speaking of
the time of the end, prophesied:“Behold I will send you Elijah the prophet before the coming of
the great and dreadful day of the Lord.” (Malachi 4:5). This was the very land, Persia, in which Daniel beheld.”… one like the Son of man came with the clouds of heaven…” (Daniel 7:13).
The Báb foretold that this great Redeemer would appear
exactly nine years after his own coming. He would, therefore, as prophesied in the
Old Testament, ‘suddenly come to his temple’. He would thus come just as Christ had so often emphasized in the
Book of Revelation: “Behold I come quickly.”
Malachi, who called it the great and dreadful day of the Lord, foretold the appearance of two at
the time of the end, saying:“Behold, I will send
my messenger, and he shall prepare the way before me: and
the Lord, whom ye seek, shall suddenly come to his temple …” (Malachi 3:1). The Báb repeatedly said that he was the
Dawn, but that the
Promise of all Ages Who was soon to come after him would be the
Sun. He foretold that this great world Saviour would usher in an age of unprecedented progress and peace.”

Bahá'u'lláh claimed that his mission as the Promised One of the
Báb, was revealed to Him in
1853 while imprisoned in the
Síyáh-Chál in
Tehran,
Iran.
[4] After his release from the Síyáh-Chál, Bahá'u'lláh was banished from Persia, and he settled in
Baghdad, which became the centre of Bábí activity. Although he did not openly declare this prophetic mandate, he increasingly became the leader of the Bábí community.

Baha’u’llah became aware of His revelation from God in the Black Pit prison in
1853, exactly nine years after the Bab foretold the great Redeemer would appear:
A revelation from God
The Bab was a Manifestation of God (Messenger) in His own right, so He was the first resurrection. He referred to the revelation of Baha’u’llah as the Latter Resurrection, and granted the Babis a respite of 19 years to be able to recognize Baha’u’llah, because the Bab knew that Baha’u’llah would publicly declare His Mission in1863. That is written in the second paragraph of
Selections From the Writings of the Báb, pp. 6-7.
“This is a letter from God, the Help in Peril, the Self-Subsisting, unto God, the Almighty, the Best Beloved, to affirm that the Bayán and such as bear allegiance to it are but a present from me unto Thee and to express my undoubting faith that there is no God but Thee, that the kingdoms of Creation and Revelation are Thine, that no one can attain anything save by Thy power and that He Whom Thou hast raised up is but Thy servant and Thy Testimony. I, indeed, beg to address Him Whom God shall make manifest, by Thy leave in these words: ‘Shouldst Thou dismiss the entire company of the followers of the Bayán in the Day of the Latter Resurrection by a mere sign of Thy finger even while still a suckling babe, Thou wouldst indeed be praised in Thy indication. And though no doubt is there about it,
do Thou grant a respite of nineteen years as a token of Thy favour so that those who have embraced this Cause may be graciously rewarded by Thee. Thou art verily the Lord of grace abounding.”
Selections From the Writings of the Báb, pp. 6-7
Context is everything. There is no reason why the word "woe" would refer to
the same things in different verses of the Bible.
The Baha'i interpretation of the three woes in the book of Revelation:
“The second woe is past; and, behold, the third woe cometh quickly.”
22 The first woe is the appearance of the Prophet, Muhammad, the son of ‘Abdu’lláh—peace be upon Him!
The second woe is that of the Báb—to Him be glory and praise!
The third woe is the great day of the manifestation of the Lord of Hosts and the radiance of the Beauty of the Promised One. The explanation of this subject, woe, is mentioned in the thirtieth chapter of Ezekiel, where it is said: “The word of the Lord came again unto me, saying, Son of man, prophesy and say, Thus saith the Lord God; Howl ye, Woe worth the day! For the day is near, even the day of the Lord is near.”
23
Therefore, it is certain that the day of woe is the day of the Lord; for in that day woe is for the neglectful, woe is for the sinners, woe is for the ignorant. That is why it is said, “The second woe is past; behold the third woe cometh quickly!” This third woe is the day of the manifestation of Bahá’u’lláh, the day of God; and it is near to the day of the appearance of the Báb.
“And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of His Christ; and He shall reign for ever and ever.”

Now look at how some Christians interpret the woes in the book of Revelation.

Of course the Baha'i interpretation is going to be different, since Baha'is do not believe what Christians believe, it is so different!
However, the Christians got the third woe right... The third woe is the return of Christ, when God's kingdom will be established on earth..
The third woe is revealed after the seventh trumpet judgment. This woe is parallel to the trumpet that sounds in
Joel 2 and signals the consummation of God’s plan for the entire world. This third woe marks the finishing of God’s judgment on sin; it occupies the book of Revelation through the 19th chapter, when Christ’s Kingdom is established on earth. Incorporated within this third and final woe are the seven “bowls” of God’s wrath, described in
Revelation 16:1-21. This series of judgments is the greatest horror the citizens of earth have ever seen. Jesus said, “If those days had not been cut short, no one would survive” (
Matthew 24:22).

Christians got it right except for one thing -- Jesus Christ’s Kingdom is never going to be established on earth because Jesus said He was no more in this world and His work was finished here (
John 14:19,
John 16:10,
John 17:4,
John 17:11,
John 19:30)
Jesus’ work was
finished when He died on the cross,
John 19:30 but Christians could not face that so they tried to bring Jesus back to life by writing stories saying that Jesus rose from the dead.
But the important thing is that Jesus never promised to return to earth, not once in the New Testament. Jesus said His work was finished here and He was no more in the world. That means that the return of Christ has to be another Person.
