As to when such a convention, an Article V Convention authorized by Article V, will occur, the answer is anytime. The public record of applications, which can be read at FOAVC (see related links), shows that 49 states have submitted more 700 applications for a convention. Congress is required to call a convention when two-thirds (34) of the states submit at least one application for a convention call. Therefore, the answer is any time.
Article V
The Congress, whenever two thirds of both Houses shall deem it necessary, shall propose Amendments to this Constitution, or, on the Application of the Legislatures of two thirds of the several States, shall call a Convention for proposing Amendments, which, in either Case, shall be valid to all Intents and Purposes, as Part of this Constitution, when ratified by the Legislatures of three fourths of the several States, or by Conventions in three fourths thereof, as the one or the other Mode of Ratification may be proposed by the Congress; Provided that no Amendment which may be made prior to the Year One thousand eight hundred and eight shall in any Manner affect the first and fourth Clauses in the Ninth Section of the first Article; and that no State, without its Consent, shall be deprived of its equal Suffrage in the Senate.
In respect to the founding and development of American government, it is (and was) possible for a constitutional convention to occur when and where enough influential leaders have judged that America was in need of it. Such a judgment occurred in the late 1780s, with a formal convention held in 1787 that was followed by a long process of ratification that concluded two years later -- in 1789 -- at which point the Constitution came formally into effect in America.

The Constitution was written in Philadelphia State House (not Delaware) between May and September of 1787. Signing did occur on September 17. While it was probably forwarded to Congress, it was the Congress under the Articles of Confederation which had been scrapped in favor of the Constitutional Convention. Technically, the document was forwarded to independent ratifying conventions in each state and fully ratified in early 1789.
