Calculate if a place is open based on the hours returned from the Google Places API

isOpenNow.js

function isOpenNow(place) {
  const date = new Date();
  const day = date.getDay();
  const hours = date.getHours();
  const minutes = date.getMinutes();
  const currentTime = (day * 24 + hours) * 60 + minutes;
  // calculate the current number of minutes into the week

  let currentlyOpen = false;

  const days = place.opening_hours.periods;
  for (let i = 0; i < days.length; i++) {
    const openTime =
      (days[i].open.day * 24 + days[i].open.hours) * 60 +
      days[i].open.minutes;
    const closeTime =
      (days[i].close.day * 24 + days[i].close.hours) * 60 +
      days[i].close.minutes;
    // check to see if the current time into the week is between the 
    // opening and closing time values for each day of the week
    if (currentTime >= openTime && currentTime < closeTime) {
