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 an half." (Daniel 12:5-7) In Biblical symbology a time means a year of twelve months of thirty days each, or 360 days.

Each day is considered for a year, as the Prophet says: "I have appointed thee each day for a year".

(Ezekiel 4:6) Here are mentioned, then, three and a half times of 360 prophetic days each, or a total of 1260 prophetic days, equal to 1260 years.

The Prophet then was shown that the 1260 years would mark the beginning of the time of the end of this beastly order.
