In an action to recover commissions under a contract for the sale of land, proof that the contract was made on the exact date alleged is not required, since, while it is necessary to allege the date with convenient certainty, it is sufficient if shown to have been prior to the consummation of the sale and within the time prescribed by the statute of limitations.
