Your collection isn't buying you anything here since you will still need to
manually delete the memory allocated. You could achieve the same effect
with:

#include <iostream>
using namespace std;

struct Time
{
    int date;
    int hour;
    int minutes;
};

int main()
{
    int MAX;
    cin >> MAX;
    Time *sept= new Time[MAX];

    for(int i=0;i<MAX;i++)
    {
        sept[i].date=i+5;
    }
    // later
    delete [] sept;

    return 0;
}

Alternatively, you could use a container to avoid manual memory allocation.

#include <iostream>
#include <vector>
using namespace std;

struct Time
{
    int date;
    int hour;
    int minutes;
};

int main()
{
    int MAX;
    cin >> MAX;
    vector<Time> sept(MAX, Time());

    for(int i=0;i<MAX;i++)
    {
        sept[i].date=i+5;
    }
    // no delete required

    return 0;
}

If the size of MAX may change during the running of the program, then the
member functions resize() or, as you indicated, push_back() may be used.
