The correct form is 'from', without the grave accent shown by example 1). It must be remembered that before verbs, including 'leave', there is no crasis, observe the examples:
From from May I start jogging in the mornings.
The price of gasoline is from 5 reais a litre.
This occurs because we do not have the junction of two 'to the' (one referring to preposition and another referring to definite article, where a + a = à) before verbs that indicates the crasis, more specifically, we have no article before verbs, just the preposition, as well as other cases of verbs presented below:
It started to rain yesterday.
all started to eat by noon.
So, don't forget the rules for using the crase so you don't make mistakes in tests and essays or even in your advertisement for the sale of a product.
