I am trying to pull data (some transaction related data) from DB. To pull the data, I am passing start date and end date as an argument to the query.
Here I need to pull the data of last 2 months. i.e., Start time would be Jun 01, 2022 and End time would be Aug 01, 2022.
Below is the script:
#!/usr/bin/perl
use strict;
use warnings;
use DateTime;
use Date::Format;
use Date::Parse;
my $nowdate = DateTime->now(time_zone => 'local');
my ($month, $year) = ($nowdate->month, $nowdate->year);
my $date = DateTime->new(
year => $year,
month => $month,
day => 1,
);
my $end_time = str2time($date);
print "END:$end_time\n";
print time2str("%d-%m-%Y %T", $end_time)."\n"; #printing just to see in human readable format
my $start_time = $date->clone;
$start_time->add( months => 1 )->subtract( days => 92 );
$start_time = str2time($start_time);
print "START:$start_time\n";
print time2str("%d-%m-%Y %T", $start_time)."\n"; #printing just to see in human readable format
I have two issues over here:
I am using DateTime object two times to get end time. Can it be done in one shot?
$start_time->add( months => 1 )->subtract( days => 92 ); In this line of code, I have to explicitly mention subtract 92 days, which wouldn't be right always. Since some months have 30 days or 31 days or even 29 days. How can I get 2 month's beginning day date?
Another example: Lets assume if we are in September 2022, then Start time and End time would be Jul 01, 2022 and Sep 01, 2022 respectively.
Note: Perl version is 5.16.3
It would be good If I can do it with Core modules which comes with 5.16.3
You could simplify it by using truncate(to => 'month') to get to the first in the current month:
my $end = DateTime->now(time_zone => 'local')
->truncate(to => 'month');
This may however fail on a day without a midnight so this may be an option:
my $end = DateTime->now(time_zone => 'local')
->set_time_zone('floating')
->truncate(to => 'month');
Then subtract the number of months to get the start date:
my $start = $end->clone->subtract( months => 2 );
Then:
my $start_time = str2time($start);
my $end_time = str2time($end);
print "START:$start_time\n";
print time2str("%d-%m-%Y %T", $start_time)."\n";
print "END:$end_time\n";
print time2str("%d-%m-%Y %T", $end_time)."\n";
Possible output:
START:1654034400
01-06-2022 00:00:00
END:1659304800
01-08-2022 00:00:00
formatCalendarDate = function (dateTime) {
return moment.utc(dateTime).format('LLL');
};
It displays: "28 februari 2013 09:24"
But I would like to remove the time at the end. How can I do that?
I'm using Moment.js.
Sorry to jump in so late, but if you want to remove the time portion of a moment() rather than formatting it, then the code is:
.startOf('day')
Ref: http://momentjs.com/docs/#/manipulating/start-of/
Use format('LL')
Depending on what you're trying to do with it, format('LL') could do the trick. It produces something like this:
Moment().format('LL'); // => April 29, 2016
The correct way would be to specify the input as per your requirement which will give you more flexibility.
The present definition includes the following
LTS : 'h:mm:ss A',
LT : 'h:mm A',
L : 'MM/DD/YYYY',
LL : 'MMMM D, YYYY',
LLL : 'MMMM D, YYYY h:mm A',
LLLL : 'dddd, MMMM D, YYYY h:mm A'
You can use any of these or change the input passed into moment().format().
For example, for your case you can pass moment.utc(dateTime).format('MMMM D, YYYY').
Okay, so I know I'm way late to the party. Like 6 years late but this was something I needed to figure out and have it formatted YYYY-MM-DD.
moment().format(moment.HTML5_FMT.DATE); // 2019-11-08
You can also pass in a parameter like, 2019-11-08T17:44:56.144.
moment("2019-11-08T17:44:56.144").format(moment.HTML5_FMT.DATE); // 2019-11-08
https://momentjs.com/docs/#/parsing/special-formats/
You can also use this format:
moment().format('ddd, ll'); // Wed, Jan 4, 2017
formatCalendarDate = function (dateTime) {
return moment.utc(dateTime).format('LL')
}
Look at these Examples.
Format Dates
moment().format('MMMM Do YYYY, h:mm:ss a'); // December 7th 2020, 9:58:18 am
moment().format('dddd'); // Monday
moment().format("MMM Do YY"); // Dec 7th 20
moment().format('YYYY [escaped] YYYY'); // 2020 escaped 2020
moment().format(); // 2020-12-07T09:58:18+05:30
Relative Time
moment("20111031", "YYYYMMDD").fromNow(); // 9 years ago
moment("20120620", "YYYYMMDD").fromNow(); // 8 years ago
moment().startOf('day').fromNow(); // 10 hours ago
moment().endOf('day').fromNow(); // in 14 hours
moment().startOf('hour').fromNow(); // an hour ago
Calendar Time
moment().subtract(10, 'days').calendar(); // 11/27/2020
moment().subtract(6, 'days').calendar(); // Last Tuesday at 9:58 AM
moment().subtract(3, 'days').calendar(); // Last Friday at 9:58 AM
moment().subtract(1, 'days').calendar(); // Yesterday at 9:58 AM
moment().calendar(); // Today at 9:58 AM
moment().add(1, 'days').calendar(); // Tomorrow at 9:58 AM
moment().add(3, 'days').calendar(); // Thursday at 9:58 AM
moment().add(10, 'days').calendar(); // 12/17/2020
Multiple Locale Support
moment.locale(); // en
moment().format('LT'); // 9:58 AM
moment().format('LTS'); // 9:58:18 AM
moment().format('L'); // 12/07/2020
moment().format('l'); // 12/7/2020
moment().format('LL'); // December 7, 2020
moment().format('ll'); // Dec 7, 2020
moment().format('LLL'); // December 7, 2020 9:58 AM
moment().format('lll'); // Dec 7, 2020 9:58 AM
moment().format('LLLL'); // Monday, December 7, 2020 9:58 AM
moment().format('llll'); // Mon, Dec 7, 2020 9:58 AM
Whenever I use the moment.js library I specify the desired format this way:
moment(<your Date goes here>).format("DD-MMM-YYYY")
or
moment(<your Date goes here>).format("DD/MMM/YYYY")
... etc I hope you get the idea
Inside the format function, you put the desired format. The example above will get rid of all unwanted elements from the date such as minutes and seconds
With newer versions of moment.js you can also do this:
var dateTime = moment();
var dateValue = moment({
year: dateTime.year(),
month: dateTime.month(),
day: dateTime.date()
});
See: http://momentjs.com/docs/#/parsing/object/.
You can use this constructor
moment({h:0, m:0, s:0, ms:0})
http://momentjs.com/docs/#/parsing/object/
console.log( moment().format('YYYY-MM-DD HH:mm:ss') )
console.log( moment({h:0, m:0, s:0, ms:0}).format('YYYY-MM-DD HH:mm:ss') )

For people like me want the long date format (LLLL) but without the time of day, there's a GitHub issue for that: https://github.com/moment/moment/issues/2505. For now, there's a workaround:
var localeData = moment.localeData( moment.locale() ),
llll = localeData.longDateFormat( 'llll' ),
lll = localeData.longDateFormat( 'lll' ),
ll = localeData.longDateFormat( 'll' ),
longDateFormat = llll.replace( lll.replace( ll, '' ), '' );
var formattedDate = myMoment.format(longDateFormat);
Try this:
moment.format().split("T")[0]
The thing is - you can run into an issue with timezones. For example, if you parse date like this: '2022-02-26T00:36:21+01:00' it may turn into '25/02/2022' As a solution if your date is in ISO format you can just cut off the time portion from the string, like this:
moment('2022-02-26T00:36:21+01:00'.split('T')[0]).utc().format('DD/MM/YYYY')
This solution is quite blunt, so be careful with string format.
This format works pretty fine
const date = new Date();
const myFormat= 'YYYY-MM-DD';
const myDate = moment(date, 'YYYYMMDDTHHmmss').format(myFormat);
Try
new Date().toDateString()
Result - "Fri Jun 17 2022"
This worked perfectly for me:
moment().format('YYYY-MM-DD')
moment(date).format(DateFormat)
Here DateFormat should be DateFormat = 'YYYY-MM-DD'
When converting time to UTC its showing one hour less than expected
I am updating a variable of dot net via moment to convert the time & show local system time to user. But post conversion i am getting one hour less. Tried utcOffset but getting error utcOffset is not a function. any suggestion
Where formData.SubmittedDate = "6/7/2019 5:44:59 AM"
$('[data-utcdate]').each(function () {
var d = moment($(this).attr('data-utcdate'));
//var isDST = d.utc().local().isDST();
//var d = moment(d).utcOffset(d);
d = d.utc();
$(this).html(d.format('MMM D, YYYY h:mm A'));
})
Getting :Jun 7, 2019 12:14 AM
Expected : Jun 7, 2019 11:44 AM
From the docs:
Get the UTC offset in minutes.
So you could use a manipulation method like add with it:
$('[data-utcdate]').each(function () {
var d = moment($(this).attr('data-utcdate'));
var offset = d.utcOffset() // will return the offset in minutes
var time = d.add(offset, "m");
$(this).html(time.format('MMM D, YYYY h:mm A'));
})
I have an date string as : Wed Aug 30 2017 00:00:00 GMT+0530 (IST) and I want to convert it into like this: 2017-8-30
Now I am doing this:
moment($scope.date.selectedDate).format('YYYY-M-DD') and it is giving the right time but throws a warning as :
moment construction falls back to js date
As the input is JS date so you need to pass input format as well. This can be done by:
moment('Wed Aug 30 2017 00:00:00 GMT+0530', 'ddd MMM DD YYYY HH:mm:ss GMT+-HH:mm').format('YYYY-M-DD');
https://jsfiddle.net/o01ktajp/1/
Relative to the warning you can refer to this post Deprecation warning: moment construction falls back to js Date.
The easiest solution would be to pass the date string in the ISO format.
As for the date, if you simply want to display the date in the UI with that format you can use the 'date' angular filter: https://docs.angularjs.org/api/ng/filter/date.
In your case you could use it like this:
$scope.date.selectedDate | date: 'YYYY-M-DD'
Br,
You can do:
var d = new Date('Wed Aug 30 2017 00:00:00 GMT+0530');
var formated = moment(d).format('YYYY-M-DD');
The ISO week numbers are not right when trying to display them on the x-axis using tickformat.
var parseDate = d3.time.format("%Y%W").parse;
var x = d3.time.scale().range([0, width]);
x.domain([parseDate("201552"), parseDate("201602")]);
var xAxis = d3.svg.axis().scale(x)
.orient("bottom")
.ticks(d3.time.monday,1)
.tickFormat(d3.time.format("%W"))
This works fine with most of the scenario except with years that have 53 weeks.
Example: from week 201552 to week 201602. In this scenario it always skips week 53 so the the tick I get are [52, 01, 02]. although the expected output is [52,53,01,02]. Here is my code
I also tried parsing the date string using momentjs since I face this problem skip week in d3.time.format
This is the modified code using momentjs to parse the date:
var parseDate = function(d){
return moment(d, "YYYYWW").toDate();
}
x.domain([parseDate("201552"), parseDate("201602")]);
var MultiFormat = d3.time.format.multi([
["%W", function(d) {
return moment(d).isoWeek();
}],
]);
var xAxis_weeks = d3.svg.axis().scale(x)
.orient("bottom")
.ticks(d3.time.monday,1)
.tickFormat( function(d) {return MultiFormat(d);})
Now the output is [51,52,01,02] which also should have been [52,53,01,02]
