Time and Place of Elijah and Moshiach

Our sages teach us that Moshiach is born on Tisha B'Av. Could Tisha B'Av also be a reference to a year and a place? 

Often in gematria, we add a definite article. In this case, תשעה באב becomes התשעי באב, the Ninth of Av. Counting the ה separately, that’s numerical value for this coming year, 5785: ה״תשפה.

Furthermore, the letters of התשעי באב could also be the number and initials for a place (switching around the letters slightly):

770, Brooklyn, New York, United States: 

תשע , ברוקלין, יורק החדש, ארצות ברית 

770 is also the Gematria of the name of the Lubavitcher Rebbe: 

רב מנחם מנדל בן לוי יצחק

5+785 is also the Gematria of “Then, Elijah the Tishbite will come:”

אז יבא אליהו התשבי
