each period of ordinary days by the number of days in a sidereal year we obtain the actual length of each prophetic period. In arranging these periods, the starting point was May 4th B.C. 141, or day on which the Temple precincts were cleansed by Simon Maccabeus. The 1290 days carries us directly to May 24th A.D. 33, which was the day of Pentecost "that great and notable day of the Lord" when the Holy Spirit descended upon the disciples at Jerusalem. It is interesting to note in this case how very precise is the language of Scripture. The passage reads:--"When the day of Pentecost was FULLY come." After their return from Babylon the Jews were accustomed to devote two days, instead of one, to the observance of the feast, and as Pentecost that year fell on May 23rd and 24th, the day of Pentecost was FULLY come on the day indicated by our chart. The event therefore happened precisely as foretold by the heavenly visitor, who said to Daniel, "the vision of the evening and the morning which was told is TRUE," and it came about with that degree of exactness with which astronomers become familiar in their study of the heavenly bodies. The chart clearly proves that the "1290 days" is a perfect fit between two well-known dates. The other periods give us two extremely important dates heretofore absolutely unknown to Bible students.
