When a circuit is connected to a battery, then electrons flow from the anode: negative terminal to the positive terminal: cathode. That happens because there is a potential difference between the two terminals. That is like water flowing from a higher location to a lower location. As cathode is at a higher potential than anode, charge is supposed to flow from cathode to anode.
For convenience of formulas and by convention the direction of current is decided to be the direction of positive charge from higher potential to lower potential.
But in reality positive charges do not flow in conductors. Only electrons move along the wires or conductors. In solutions positive and negative charges flow.
Thus it is by convention that flow direction of positive charges is chosen to be the direction of conventional current. It is by convenience and convention. Thus the flow of current happens to be the opposite direction to that of electron flow in conductors. This is the convention chosen by the inventors and discoverers like Benjamin Franklin, Thomas Alva Edison and others at that time.
In some situations in semiconductors or solutions, the positive charges move and negative charges (need not be electrons only) move simultaneously in opposite directions. In that case too the direction of current is defined as the direction of positive charges.
