Generating 7 days in a week as formatted object

so I am using the momentJS library as the moment to create an array of 7 days in a week like this:
const moment = require('moment')
var startOfWeek = moment().startOf('week');
var endOfWeek = moment().endOf('week');
var days = [];
var day = startOfWeek;
while (day <= endOfWeek) {
days.push(day.format("MMMM ddd DD, YYYY "));
day = day.clone().add(1, 'd');
}
console.log(days);
And the result return an array of 7 days a week like this:
["December Sun 25, 2022 ","December Mon 26, 2022 ", "December Tue 27, 2022 " , "December Wed 28, 2022 ", "December Thu 29, 2022 ", "December Fri 30, 2022 ", "December Sat 31, 2022 "]
But the result that I look for is something like this:
const weekday = [
{
day: Mon,
date: 26
},
{
day: Tue,
date: 27
},
{
day: Wed,
date: 28
},
{
day: Thu,
date: 26
},
{
day: Fri,
date: 26
},
{
day: Sat,
date: 26
},
]
I am stuck on how to convert the data, could anyone able to help me ? Thanks

Without momentjs, you can use toLocaleDateString and other native Date methods to achieve the result:
const day = new Date(); // Today
day.setDate(day.getDate() - day.getDay() - 1); // Most recent Saturday (not today)
const weekday = Array.from({length: 7}, () => (
day.setDate(day.getDate() + 1), {
day: day.toLocaleDateString("en-US", { weekday: "short" }),
date: day.getDate(),
}
));
console.log(weekday);

If you wish to keep the original output to use elsewhere and not modify the original code, you can map over the days array and construct a new array based on the formatted string (converting to an integer as necessary).
const days = ["December Sun 25, 2022 ", "December Mon 26, 2022 ", "December Tue 27, 2022 ", "December Wed 28, 2022 ", "December Thu 29, 2022 ", "December Fri 30, 2022 ", "December Sat 31, 2022 "]
const weekday = days.map((formattedDate) => {
const [_, day, dateString] = formattedDate.split(" ");
return {
day,
date: parseInt(dateString)
};
});
console.log(weekday);
Alternatively, you can modify your original code
//const moment = require('moment')
const startOfWeek = moment().startOf('week');
const endOfWeek = moment().endOf('week');
// uncomment if you still want `days`
// const days = [];
const weekday = [];
let day = startOfWeek;
while (day <= endOfWeek) {
// days.push(day.format("MMMM ddd DD, YYYY "));
weekday.push({ day: day.format("ddd"), date: day.date() });
day = day.clone().add(1, 'd');
}
console.log(weekday);

Why is momentjs converting the time zone the wrong way?

I have a form that schedules events. Part of the form is setting the event start time. The form has selection fields for Date, Time, and Timezone. I use this information with momentJS to build a dateTime called eventTime. The form should not submit if the selected DateTime is in the past. So I wrote some simple logic that says:
timeDiff = moment(eventTime).diff(currentTime).
If timeDiff is less than zero the no submit.(More below) This is fine but I am having issues with timezones. So here is what I am trying to do:
If I currently reside in EST and it is 2:00pm then my form should not submit if select 1:45 EST on the given day. But if I change the "Time Zone" dropdown to "Central Time" Then it should submit. Assuming I am not thinking incorrectly
1:45 CST = 2:45 EST
Therefore since it is currently 2:00 CST the form should submit, but momentJS is going the other way and it is thinking the time is 1:45 EST. Based on the moment objects below (in UTC time) I would expect "Central Zone Moment Object" to be Thu Jun 25 2020 10: 45: 00 GMT instead of Thu Jun 25 2020 08: 45: 00 GMT what am I missing.
Thanks
let date = "2020-06-25";

let eventTimeCST = moment.tz(moment(date).set({ "hour": time.substring(0, 2), "minute": time.substring(3, 5) }), timezoneCST);
timeDiff = moment([eventTimeEST or eventTimeCST]).diff(currentTime)
if (timeDiff > 0) {
// allow submit
}
console.log(eventTimeEST)

let currentTime = moment().tz(moment.tz.guess());
let eventTimeEST = moment.tz(moment(date).set({ "hour": time.substring(0, 2), "minute": time.substring(3, 5) }), timezoneEST);
let eventTimeCST = moment.tz(moment(date).set({ "hour": time.substring(0, 2), "minute": time.substring(3, 5) }), timezoneCST);
This code is basically setting a date in your current TZ and then translating it into another timezone (America/New York-America/Chicago).
The second statement is basically doing EDT to EDT.
The third statement is doing EDT to CDT.
That's why it goes back an hour. Because 1:45 PM EDT is 12:45 PM CDT.
But what you really want to do is to get the time at that timezone.
Eg. 1:45 PM CDT.
The way you do it is by basically setting the time on that timezone.
let date = "2020-06-25";
let timezoneEDT = "America/New_York";
let timezoneCDT = "America/Chicago";
let notBefore = { hour : 14, minute : 0 };
let clock = { hour : 13, minute : 45 };
let a = moment(date).tz(timezoneEDT).set(notBefore); //14:00 EDT
let b = moment(date).tz(timezoneCDT).set(clock); //13:45 CDT -> 14:45 EDT
let c = moment(date).tz(timezoneEDT).set(clock); //13:45 EDT
console.log(test(a, b)); //14:00 EDT against 14:45 EDT prints valid
console.log(test(a, c)); //13:45 EDT against 14:00 EDT prints invalid
function test(a,b){
return a.diff(b) > 0 ? 'Invalid date' : 'Valid date';
}

As expected
let eventTimeCST = moment.tz(moment(date).set({ "hour": time.substring(0, 2), "minute": time.substring(3, 5) }), timezoneCST);
creates a moment object in my timezone (EST) and the .tz adjusts that time zone. I needed to create a new moment object in the CST timeZone, compare it to my timezone.
That can be achieved like;
let eventTimeCST = moment.tz({'year': 2020, 'month': 06, 'day': 26, 'hour': 9, 'minute': 30}, timezoneCST)
So I just parsed out date and time and built the object.
FYI replacing
{'year': 2020, 'month': 06, 'day': 26, 'hour': 9, 'minute': 30}
with
date + " " time
also worked but threw a deprecation warning

Return the values that occurred multiple times using google apps script

I have multiple values in a column and I wan to return the values which occurred 5 times. sample data:
Date Column
Row1: July 1, 2019
Row2: July 1, 2019
Row3: July 1, 2019
Row4: July 1, 2019
Row5: July 1, 2019
Row6: July 5, 2019
Row7: July 5, 2019
Row8: July 5, 2019
Row9: July 5, 2019
Row10: July 5, 2019
Row11: July 10, 2019
Row12: July 12, 2019
I have tried some of the solutions I got from this site. One (Amit Agarwal) almost answered my question, unfortunately, his code was only to display the values with the maximum occurrence. Using my code and (mostly) his code, this is the result:
function countDate() {
var ss = SpreadsheetApp.openByUrl(url);
var ws = ss.getSheetByName("Test_Data");
var dateRg = ws.getRange(1, 1, ws.getLastRow(), 1).getDisplayValues();
var data = {}
for (var i = 0; i < dateRg.length; i++) {
data[dateRg[i]] = data[dateRg[i]] || 0;
data[dateRg[i]]++;
}
var max = Object.keys(data).reduce(function(a, b) {
return data[a] > data[b] ? a : b
});
ws.getRange(2, 4).setValue(max);
}
I want to get all the values that occurred 5 times from my list or column (google sheet). I honestly have no knowledge on how to do it. I'm so newbie in programming. I asked this question here already but no one is answering anymore, so I ended up asking it again and I really need a solution soon. I humbly ask anyone for help.

Here you go
var Date_Field = [
'July 1, 2019',
'July 1, 2019',
'July 1, 2019',
'July 1, 2019',
'July 1, 2019',
'July 5, 2019',
'July 5, 2019',
'July 5, 2019',
'July 5, 2019',
'July 5, 2019',
'July 10, 2019',
'July 12, 2019'
];
var CheckLimitReached = function (T) {
var records = {};
T.forEach(function (x) { records[x] = (records[x] || 0) + 1; });
var limit_reached = Object.keys(records).filter(function (R) {
return records[R] >= 5;
});
return limit_reached;
};
console.log(CheckLimitReached(Date_Field));

Sort array of days in ascending order

I have an array that contains unique strings of day names. The day names will be in random order. - eg:
["Sun 10am", "Sat 4pm", "Sat 10am", "Wed 3pm", "Sun 4pm"]
I want to use javascript to sort that array so that it will be in ascending order.
["Wed 3pm", "Sat 10am", "Sat 4pm", "Sun 10am", "Sun 4pm"]
Can anybody suggest the best way to do that?
Thank you

You can create a object with days names as keys and values increasing from 1 to 7.
Create a helper function which takes second part of string i.e 3pm,10am.. as input and add 12 to result if its pm
Also divide the result by 24 so first sort should happen on days.
Use the sort() function and for each value add the time index(which will be always less than 1) to the day index(1,2,3...) and subtract it for both value.
const arr = ["Sun 10am", "Sat 4pm", "Sat 10am", "Wed 3pm", "Sun 4pm"];
function getTime(str){
let time = str.slice(0,-2);
let isAm = str.includes('am');
return (isAm ? +time : +time + 12)/24
}
function sortTime(arr){
let days = {
Mon:1,
Tue:2,
Wed:3,
Thur:4,
Fri:5,
Sat:6,
Sun:7
}
return arr.slice().sort((a,b) => {
let [day1,time1] = a.split(' ');
let [day2,time2] = b.split(' ');
return (days[day1] + getTime(time1)) - (days[day2] + getTime(time2))
})
}
console.log(sortTime(arr))

You could take an object for the values of the day and sort by the time.
const
getTime = string => {
var [day, hour, meridian] = string.match(/^(\D{3}) (\d+)(am|pm)/).slice(1),
days = { Mon: 1, Tue: 2, Wed: 3, Thu: 4, Fri: 5, Sat: 6, Sun: 7 };
return days[day] * 24 + +hour + (meridian === 'pm' && 12) + (hour === '12' && -12);
};
var array = ["Sun 10am", "Sat 4pm", "Sat 10am", "Wed 3pm", "Sun 4pm", "Sat 12pm", "Sat 12am"];
array.sort((a, b) => getTime(a) - getTime(b));
console.log(array);

You can use the combination of map and sort. Here I am converting time in 24 Hours format for easy comparison of numbers.
var array = ["Sun 10am", "Sat 4pm", "Sat 10am", "Wed 3pm", "Sun 4pm"],
mapping = { Mon: 1, Tue: 2, Wed: 3, Thu: 4, Fri: 5, Sat: 6, Sun: 7 },
result = array
.map((time, i) => {
const hour = parseInt(time.split(" ")[1], 10);
const hour24 = time.indexOf("am") > -1 ? hour : hour + 12;
return {
index: i,
day: mapping[time.split(" ")[0]],
hour24
}
})
.sort((a, b) => a.day - b.day || a.hour24 - b.hour24)
.map(({
index
}) => array[index]);
console.log(result);

How to merge days with similar opening hours

I'm trying to write a javascript function to merge days with similar opening hours of a store together. For example, if we have:
"hours": [
"Friday 11:00am - 3:00pm, 5:00pm - 10:00pm",
"Monday 11:00am - 3:00pm, 5:00pm - 9:30pm",
"Saturday 12:00pm - 10:00pm",
"Sunday 12:00pm - 9:30pm",
"Thursday 11:00am - 3:00pm, 5:00pm - 9:30pm",
"Tuesday 11:00am - 3:00pm, 5:00pm - 9:30pm",
"Wednesday 11:00am - 3:00pm, 5:00pm - 9:30pm"
],
I want the code to simplify it to:
"hours": [
"Mo-Sa 11:00-14:30",
"Mo-Th 17:00-21:30",
"Fr-Sa 17:00-22:00"
],
Is there a way of accomplishing this without a long list of if/else or case statements?

Go functional and save a lot of mess.
Assuming that this is your data:
var data = [
{day: "Mon", open: 900, close: 1700},
{day: "Tue", open: 900, close: 1700},
{day: "Wed", open: 700, close: 1700},
{day: "Thu", open: 900, close: 1700},
{day: "Fri", open: 900, close: 1700},
{day: "Sat", open: 900, close: 1900},
{day: "Sun", open: 900, close: 1900},
];
You can simply reduce the array to a merged array in 6 lines of code:
var merged = data.reduce(function(preVal, curVal) {
var last = preVal[preVal.length - 1];
if (last && last.open == curVal.open && last.close == curVal.close) {
last.endDay = curVal.day;
} else {
preVal.push(curVal);
}
return preVal;
}, []);
And just in case for debugging:
for (var i in merged) {
var m = merged[i];
var endDay = m.endDay ? " to " + m.endDay : "";
console.log(m.day + endDay + " " + m.open + "-" + m.close);
}
BONUS Now, if you have to convert merged into a different format (e.g., something that you need to print on the screen) you can go functional again and map the merged into whatever format you want:
var mergedNewFormat = merged.map(function(v) {
return {
days: [v.day, v.endDay ? v.endDay : v.day],
hours: [v.open, v.close],
};
});

I would suggest breaking your data down into a more structured format than what you currently have specified in your comments such as:
var data = [
{ day: "Mon", hours: "11:00 AM to 10:30 PM" },
{ day: "Thu", hours: "11:00 AM to 10:30 PM" },
{ day: "Tue", hours: "11:00 AM to 10:30 PM" },
{ day: "Wed", hours: "11:00 AM to 10:32 PM" },
{ day: "Fri", hours: "11:00 AM to 10:00 PM" },
{ day: "Sat", hours: "11:00 AM to 10:00 PM" },
{ day: "Sun", hours: "11:00 AM to 10:30 PM" }
];
Now you can iterate over the days and group by identical hours like this:
function collapseHours(data) {
var collapsed = [];
var idx = -1;
for(var i=0; i<data.length; i++) {
var day = data[i];
if(idx == -1 || collapsed[idx].hours != day.hours) {
collapsed.push({days:[day.day],hours:day.hours});
idx++;
} else {
collapsed[idx].days.push(day.day);
}
}
return collapsed;
}
This collapseHours(data) would produce the following:
[
{"days":["Mon","Thu","Tue"],"hours":"11:00 AM to 10:30 PM"},
{"days":["Wed"],"hours":"11:00 AM to 10:32 PM"},
{"days":["Fri","Sat"],"hours":"11:00 AM to 10:00 PM"},
{"days":["Sun"],"hours":"11:00 AM to 10:30 PM"}
];
Now you can pretty print your hours like this:
function prettyPrintHours(collapsed) {
var lines = [];
for(var i=0; i<collapsed.length; i++) {
var line = collapsed[i];
var days = line.days;
if(days.length == 1) {
lines.push(days[0]+" "+line.hours);
} else {
lines.push(days[0]+"-"+days[days.length-1]+" "+line.hours);
}
}
return lines;
}
Which will produce:
[
"Mon-Tue 11:00 AM to 10:30 PM",
"Wed 11:00 AM to 10:32 PM",
"Fri-Sat 11:00 AM to 10:00 PM",
"Sun 11:00 AM to 10:30 PM"
]
Given these two functions it should be relatively simple to customize the data format and output formatting to your exact needs.
