Parse a date and time from a string
Given the string
"2008-05-06 13:29", parse it as a date representing 6th March, 2008 1:29:00pm in the local time zone.
ruby
# With timezone info
puts Time.parse('2008-05-06 13:29')
puts Time.parse('2008-05-06 13:29')
erlang
% AFAIK, no datetime-parsing library exists; 'parse_to_datetime' is a simplistic, problem-specific hack
LocalDateTime = erlang:universaltime_to_localtime(parse_to_datetime("2008-05-06 13:29:34")),
LocalDateTime = erlang:universaltime_to_localtime(parse_to_datetime("2008-05-06 13:29:34")),
csharp
DateTime parsedDate = DateTime.Parse("2008-05-06 13:29");
// Ideally, you would catch the potential FormatException or use DateTime.TryParse in production code.

dt := DateTime.fromLocale("2008-05-06 13:29", "YYYY-MM-DD hh:mm")
Display information about a date
Display the day of month, day of year, month name and day name of the day 8 days from now.
ruby
require 'date'
next_week = Date.today + 8
puts next_week.day # day of month
puts next_week.yday # day of year
puts next_week.strftime('%B') # month name
puts next_week.strftime('%A') # day name
next_week = Date.today + 8
puts next_week.day # day of month
puts next_week.yday # day of year
puts next_week.strftime('%B') # month name
puts next_week.strftime('%A') # day name
csharp
DateTime date = DateTime.Today.AddDays(8);
Console.WriteLine("Day of month: " + date.Day);
Console.WriteLine("Day of year: " + date.DayOfYear);
Console.WriteLine("Month name: " + date.ToString("MMMM"));
Console.WriteLine("Day name: " + date.ToString("dddd"));
// The two ToString calls will use the current locale.
// To get localised month and day names, see http://msdn.microsoft.com/en-us/library/8tfzyc64.aspx
Console.WriteLine("Day of month: " + date.Day);
Console.WriteLine("Day of year: " + date.DayOfYear);
Console.WriteLine("Month name: " + date.ToString("MMMM"));
Console.WriteLine("Day name: " + date.ToString("dddd"));
// The two ToString calls will use the current locale.

date := Date.today + 8day
echo(date.day)
echo(date.dayOfYear)
echo(date.month.localeFull)
echo(date.weekday.localeFull)
echo(date.day)
echo(date.dayOfYear)
echo(date.month.localeFull)
echo(date.weekday.localeFull)
Display a date in different locales
Display a language/locale friendly version of New Year's Day for 2009 for several languages/locales. E.g. for languages English, French, German, Italian, Dutch the output might be something like:
Thursday, January 1, 2009
jeudi 1 janvier 2009
giovedì 1 gennaio 2009
Donnerstag, 1. Januar 2009
donderdag 1 januari 2009
(Indicate in comments where possible if any language specific or operating system configuration needs to be in place.)
Thursday, January 1, 2009
jeudi 1 janvier 2009
giovedì 1 gennaio 2009
Donnerstag, 1. Januar 2009
donderdag 1 januari 2009

Display the current date and time
Create a Date object representing the current date and time. Print it out.
If you can also do this without creating a Date object you can show that too.

// Creating a variable first:

Console.WriteLine(now);
// Without creating a variable:
Console.WriteLine(DateTime.Now);
DateTime now = DateTime.Now;
Console.WriteLine(now);
