Solution

  • Instead of making separate states for your date object and the current month, why not just keep the dateValue as the only state and get the month from that.

    const [dateValue, setDateValue] = useState(moment());

const increaseMonth = () => {
    setDateValue(moment(dateValue).add(1, "M"));
};

    Then, you can have the value of your month be

    dateValue.format("MMMM-YYYY")

    This has less code and you only have to update the date object and then your month will update when the days update.
