AppleScript
Idiomatic
This restores the legitimate code which has twice now been deleted by the poster of the hacks below. Explicitly: square brackets are not and have never been part of the AppleScript language and «class isot» as string is a hack someone discovered many years ago when it wasn't possible to coerce AppleScript month enums directly to integer and when AppleScript's string class used 8-bit characters. Back then, the coercion from string to «class isot» also worked. But this ended with the introduction of AppleScript 2.0 in 2007, when string, Unicode text, and text became synonymous terms for UTF-16 text. The ability to coerce from 8-bit text specifically to string was retained for compatibility with existing scripts and for reading non-Unicode text files. Other classes of text such C string were discontinued.
Whether or not they happen to work, to insist on posting code containing things which have never been part of the language without noting them as hacks, when they're entirely unnecessary, and deleting legitimate and effective code to make way for them, is seriously to misinform readers.
<lang applescript>set {year:y, month:m, day:d, weekday:w} to (current date)
tell (y * 10000 + m * 100 + d) as text to set shortFormat to text 1 thru 4 & "-" & text 5 thru 6 & "-" & text 7 thru 8 set longFormat to (w as text) & (", " & m) & (space & d) & (", " & y)
return (shortFormat & linefeed & longFormat)</lang>
- Output:
<lang applescript>"2020-10-28 Wednesday, October 28, 2020"</lang>
Hack alternative
AppleScript date objects are very simple to manipulate, provided one is familiar with the slightly unintuitive nature of how they should be handled in order to be robust and produce the desired result across all systems. Despite the official documentation claiming otherwise, AppleScript is not able to parse date strings that don’t strictly adhere to the date and time format strings specified in System Preferences—thus it is a setting that is specific to one’s system, and won’t naturally port.
AppleScript provides properties and classes specifically for manipulating or constructing date objects that are not dependent on anything outwith the AppleScript language. In most cases, the current date command provides a starting point, from which one gets current or sets new values for its day, month, year, and time properties and property classes to determine or affect the date a particular date object refers to.
Formatting is usually achieved by extracting individual date components, performing text manipulations (e.g. to prepend leading zeroes) on each of these, then concatenating these for the final result. The «class isot» class doesn’t have a vernacular form and can only be accessed using its raw chevron syntactic form, which others may recognise from similar AppleScript classes such as «class furl», «class utf8» and so forth. They can provide some useful—and, often, more reliable—features that can save the headache suffered by many when learning how the file, POSIX file, and alias classes differ between one another, and then also with the way the same class can be implemented in ways or yield unexpected results when used in a context specific to a scriptable application.
«class isot» and date class objects can coerce to and from one another. The «class isot» is an opaque data type wrapping the hexbytes of an ISO-8601 formatted datetime string. Sadly, it doesn’t permit one to use it to convert a string into hexbytes, but it is ideal for taking a date reference via the «class isot» intermediary form and coercing this to string class (whose chevron syntax form is «class TEXT»), but it will not coerce onto other AppleScript classes that are normally used interchangeably to represent strings, namely text («class ctxt») or unicode text («class utxt»).
Both scripts provided below, contributed separately by different users, each make use of the features discussed above. The first demonstrates the simplest and most direct solution, but simplicity forces specificity, which limits what other algorithmic problems it could usefully or easily be adapted to solve. The latter borrows a functional approach and favours an initial investment to create the atomic handlers that pay off by providing the reusable building blocks of identical code that will be the composable functions all other scripts are assembled from sparing much of the need to write new code to solve the vast majority of problems on this site. Generality, versatility and adaptability of this approach can be proven mathematically.
<lang applescript>tell (the current date) set shortdate to text 1 thru 10 of (it as «class isot» as string) set longdate to the contents of [its weekday, ", ", ¬ (its month), " ", day, ", ", year] as text end tell
log the shortdate log the longdate</lang>

Version 2: Meta Language
Forth is less of a language and more of an extensible toolkit of simple routines. This version attempts to demonstrate using the simple routines to extend Forth. Then using the language extensions and the power of concatenative language to solve the problem. This solution could create numerous date formats as one line definitions now that we have our "date" words defined. Typically these extensions would be saved as a library file.

- The "now" function returns the current time as a list. A time zone
- offset in minutes can be supplied. The example below is for Eastern
- Standard Time. NewLISP's implicit list indexing is used to extract
- the first three elements of the returned list (year, month and day).
(setq n (now (* -5 60))) (println "short: " (format "%04d-%02d-%02d" (n 0) (n 1) (n 2)))
- The "date-value" function returns the time in seconds from the epoch
- when used without arguments. The "date" function converts the
- seconds into a time representation specified by the format string at
- the end. The offset argument ("0" in this example) specifies a
- time-zone offset in minutes.
(println "short: " (date (date-value) 0 "%Y-%m-%d"))
- The time formatting is supplied by the underlying C library, so
- there may be differences on certain platforms. Particularly, leading
- zeroes in day numbers can be suppressed with "%-d" on Linux and
- FreeBSD, "%e" on OpenBSD, SunOS/Solaris and Mac OS X. Use "%#d" for
- Windows.
(println "long: " (date (date-value) 0 "%A, %B %#d, %Y"))
- By setting the locale, the date will be displayed appropriately

Python
Formatting rules: http://docs.python.org/lib/module-time.html (strftime)
<lang python>import datetime today = datetime.date.today()
- The first requested format is a method of datetime objects:
print today.isoformat()
- For full flexibility, use the formatting codes from the link above:
print today.strftime("%A, %B %d, %Y") </lang>
R
strftime is short for "string format time". <lang rsplus>now <- Sys.time() strftime(now, "%Y-%m-%d") strftime(now, "%A, %B %d, %Y")</lang>
Racket
Module racket/date is included within #lang racket However its date to string facilities only provide ISO-8601 (which provides the "2007-11-10" format) but nothing that strictly provides "<Full day name>, <Full month name> ...".
We therefore need to import SRFI/19 "SRFI 19: Time Data Types and Procedures" (it's a standard Racket package).
See: http://srfi.schemers.org/srfi-19/srfi-19.html
<lang racket>#lang racket (require srfi/19)
- The first required format is an ISO-8601 year-month-day format, predefined
- as ~1 in date->string
(displayln (date->string (current-date) "~1"))
- You should be able to see how each of the components of the following format string
- work...
- ~d is zero padded day of month
(displayln (date->string (current-date) "~A, ~B ~d, ~Y"))
- ~e is space padded day of month
(displayln (date->string (current-date) "~A, ~B ~e, ~Y"))</lang> both ~d and ~e satisfy the format required, since the "10" part of that date is 2-digit
- Output:
2013-04-02 Tuesday, April 02, 2013 Tuesday, April 2, 2013

(formerly Perl 6)
<lang perl6>use DateTime::Format;
my $dt = DateTime.now;
say strftime('%Y-%m-%d', $dt); say strftime('%A, %B %d, %Y', $dt);</lang>
The built-in Date and DateTime classes both offer support for the ISO format: <lang perl6>my $d = Date.today;
say $d.yyyy-mm-dd;</lang>
They don't include the longer format specified in the task, but you can always roll your own formatter instead of importing the library:
<lang perl6>my @months = <January February March April May June July
August September October November December>;
my @days = <Monday Tuesday Wednesday Thursday Friday Saturday Sunday>; my $us-long = sub ($self) { "{@days[$self.day-of-week - 1]}, {@months[$self.month - 1]} {$self.day}, {$self.year}" }; my $d = Date.today :formatter($us-long);
say $d.yyyy-mm-dd; # still works say $d; # uses our formatter sub</lang>

REXX
REXX has a number of ways to obtain the various components of the current date (indeed, any date).
It's up to the programmer to choose whatever version of the date BIF that best serves the purpose.
idiomatic version
<lang REXX>/*REXX pgm shows current date: yyyy-mm-dd & Dayofweek, Month dd, yyyy*/
x = date('S') /*get current date as yyyymmdd */
yyyy = left(x,4) /*pick off year (4 digs).*/
dd = right(x,2) /*pick off day-of-month (2 digs).*/ mm = substr(x,5,2) /*pick off month number (2 digs).*/
say yyyy'-'mm"-"dd /*yyyy-mm-dd with leading zeroes.*/
weekday = date('W') /*dayofweek (Monday or somesuch).*/ month = date('M') /*Month (August or somesuch).*/ zdd = dd+0 /*remove leading zero from DD */ say weekday',' month zdd"," yyyy /*format date as: Month dd, yyyy*/
/*stick a fork in it, we're done.*/</lang>

Wren
Unless it is embedded in a host application, Wren currently has no direct way to obtain the current date. We therefore assume this is passed in by the user as a command line parameter. <lang ecmascript>import "os" for Process import "/date" for Date
var args = Process.arguments if (args.count != 1) {
Fiber.abort("Please pass just the current date in yyyy-mm-dd format.")
} var current = Date.parse(args[0]) System.print(current.format(Date.isoDate)) System.print(current.format("dddd|, |mmmm| |d|, |yyyy"))</lang>
