I have these code that helps generate an array of times based on a start and an end time, it works well for 30 mins and less, but doesn't for 1 hour(60) and above...
export const getTimes = (start, end, timeInterval = 30) => {
if (!start || !end) return
start = parseInt(start) * 2 + (+start.slice(-2) > 0)
end = parseInt(end) * 2 + (+end.slice(-2) > 0) + 1
return Array.from({ length: end - start }, (_, i) => [
(i + start) >> 1,
((i + start) % 2) * Number(timeInterval),
]).map(([h, m]) =>
`${h % 12 || 12}:${m}${m.toString().length === 1 ? 0 : ""} ${
"AP"[+(h > 11)]
}M`.replace(/bdb/g, "0$&")
)
}
console.log(getTimes("9:00", "22:00"))
the result is
["9:00 AM","9:30 AM","10:00 AM","10:30 AM","11:00 AM","11:30 AM","12:00 PM","12:30 PM","1:00 PM","1:30 PM","2:00 PM","2:30 PM","3:00 PM","3:30 PM","4:00 PM","4:30 PM","5:00 PM","5:30 PM","6:00 PM","6:30 PM","7:00 PM","7:30 PM","8:00 PM","8:30 PM","9:00 PM","9:30 PM","10:00 PM"]
but for 1 hour(60)
["9:00 AM","9:60 AM","10:00 AM","10:60 AM","11:00 AM","11:60 AM","12:00 PM","12:60 PM","1:00 PM","1:60 PM","2:00 PM","2:60 PM","3:00 PM","3:60 PM","4:00 PM","4:60 PM","5:00 PM","5:60 PM","6:00 PM","6:60 PM","7:00 PM","7:60 PM","8:00 PM","8:60 PM","9:00 PM","9:60 PM","10:00 PM"]
Your interval should be based off of minutes. Add the minutes to the start time. Convert the total minutes to HH:MM. (note I did not do the AM/PM, you can figure that out)
function getMins(time) {
const parts = time.split(":");
return +parts[0] * 60 + +parts[1];
}
function convertMins(totalMinutes) {
const minutes = (totalMinutes % 60).toString().padStart(2, '0');
let hrs = (totalMinutes-minutes)/60;
const hours = hrs.toString().padStart(2, '0');
return `${hours}:${minutes}`;
}
function getTimes(start, end, timeInterval = 30) {
const startMins = getMins(start);
const endMins = getMins(end);
return Array.from({ length: Math.ceil((endMins - startMins) / timeInterval) + 1 })
.map((_, i) => convertMins( Math.min(startMins + i * timeInterval, endMins)));
}
console.log(getTimes("9:00", "22:00"))
console.log(getTimes("9:00", "22:00", 20))
console.log(getTimes("9:00", "22:00", 60))
console.log(getTimes("9:00", "22:00", 35))
console.log(getTimes("9:00", "22:00", 180))Thanks guys, I finally got it
function generateTime(start, end, step) {
const dt = new Date(`December 17, 1995 ${start}`);
const dc = new Date(`December 17, 1995 ${end}`);
const rc = [];
while (dt <= dc) {
rc.push(dt.toLocaleTimeString('en-US',{timeStyle: 'short'}));
dt.setMinutes(dt.getMinutes() + step);
}
return rc;
}
console.log(generateTime("9:00", "23:00", 90))
