Daniel 12.11,12 --- And from the time the daily sacrifice was removed and the silent abomination placed, is one thousand, two hundred, and ninety [years]. Fortunate is he who waits and reaches days of one thousand, three hundred, and thirty-five [years].
A difference of 45 years and this year, May 20th will mark 45 years since Yerushalayim was unified. And 2,844 years ago, Shlomo HaMelech began building the First Temple in the month of Iyar.
Once all impediments are removed, we, too, will begin to build - The Third Temple - to our God. Why shouldn't it also be in the month of Iyar - the month of Ziv - "brilliance?"
Interestingly enough, the verse (Daniel 8:14)
has the gematria of 2844.
Rashi on the verse says that the words ערב בקר from that verse are to be interpreted as gematria. Perhaps we can say that the entire verse should be interpreted as gematria. 2844 years from 2928 (the year the construction began on the first Beit Hamikdash) brings us to 5772.
Continuing with Rashi's interpretation, Rashi on the previous verse interprets וקדש as the Beit Hamikdash (unlike the Metzudat David, who says it means the holy nation). Malbim also interprets it this way. This tells us that the place that was sanctified by Shelomo Hamelech (even though the sanctification didn't start until 8.5 years later - in Tishri of 2937), whose construction started in Iyar 2928, will be (נצדק) justified 2844 years later.
May it be so.
