Format for Ordinal Dates (Day of Month with Suffixes -St, -Nd, -Rd, -Th)

display a date in particular format from month array in php

PHP got you covered :)

setlocale(LC_TIME, 'fr_FR');

$dateString = '2020-08-08';
$timestamp = strtotime($dateString);
$formattedDate = strftime('%d %B %Y', $timestamp);
//setlocale(LC_ALL, Locale::getDefault()); // restore (if neccessary)

echo utf8_encode($formattedDate);

output

08 août 2020

Working example.

To get the 1er day you can do what you already did. Just split up the strftime(or its result).

another solution (will display all days ordinally though)

$locale = 'fr_FR';
$dateString = '2020-08-01';
$date = new DateTimeImmutable($dateString);
$dateFormatter = new IntlDateFormatter(
    $locale,
    IntlDateFormatter::FULL,
    NULL
);

$numberFormatter = new NumberFormatter($locale, NumberFormatter::ORDINAL);
$ordinalDay = $numberFormatter->format($date->format('d'));
$dateFormatter->setPattern('LLLL Y');

echo $ordinalDay . ' ' . $dateFormatter->format($date->getTimestamp());

output

1er août 2020

Working example.

How to convert a date having ordinal format 1st March 1994?

You have three problems.

• First, you're trying to parse the date using the format YYYY-MM-DD. That's not the format of your data, which is why parsing is failing.
• Second, you're expecting a Date object to retain information about a particular format. It doesn't. Instead, you would parse from one text format to a Date, and then use another DateFormat (with the desired output format) to format the Date into a String. Date.toString() will always use the same format, regardless of how you arrived at the Date.
• Third, your format of YYYY-MM-DD isn't really what you want - you want yyyy-MM-dd. YYYY is the "weekyear", and DD is the "day of year".

I don't know of any SimpleDateFormat approach which would handle the ordinal part of your input string ("1st", "2nd" etc) - you'll probably need to put a bit of work into stripping that out. Once you've got a value such as "1 March 1990" you can parse with a SimpleDateFormat using the pattern d MMMM yyyy. Make sure you set the time zone and the locale appropriately.

Ordinal hour-of-day Hour Ending conversion to date-time value

Perhaps the java.time method you are looking for is truncatedTo, which can be used to take any ZonedDateTime and truncate the minutes and seconds

ZonedDateTime zdt = ZonedDateTime.now();
ZonedDateTime rounded = zdt.truncatedTo(ChronoUnit.HOURS);
ZonedDateTime hourEnd = rounded.plusHours(1);

PHP echo something based on day of month

Actually what you want to do can be done very trivial

echo (new DateTime())->format('jS'); 

or using date()

echo date('jS');

From date() manual:

S - English ordinal suffix for the day of the month, 2 characters

NSDateFormatter setDateFormat non-zero-padded month number

Use M instead of MM in the format string. If you use two letters, you specify that the result should have two digits, if you don't, the result can have one or two digits.

Formatting date to human readable format

$timestamp = "2013-09-30 01:16:06";
echo date("F jS, Y", strtotime($timestamp)); //September 30th, 2013

Note the use of S to get the english ordinal suffix for the day.

Since you're already using strtotime if you need a human readable data for the current time you can just use the keyword "now" as in strtotime("now")

Convert date to ordinal python?

You'll need to use strptime on the date string, specifying the format, then you can call the toordinal method of the date object:

>>> from datetime import datetime as dt
>>> d = dt.strptime('2010-03-01', '%Y-%m-%d').date()
>>> d
datetime.date(2010, 3, 1)
>>> d.toordinal()
733832

The call to the date method in this case is redundant, and is only kept for making the object consistent as a date object instead of a datetime object.

If you're looking to handle more date string formats, Python's strftime directives is one good reference you want to check out.

Convert date format for db

Use the date function:

$time = strtotime("Friday, 21 October, 2011");
echo date("Y-m-d", $time);

The linked page provides a good description of the available format specifiers,
and you can see the predefined datetime constants here.
