…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 Muhammad; for in the religion of Muhammad
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.”[Daniel
12:6–7]
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 Muhammad, by the reckoning of Islám. (‘Abdu’l-Baha,
