-# date.rb - date and time library
-#
-# Author: Tadayoshi Funaba 1998-2011
-#
-# Documentation: William Webber <william@williamwebber.com>
-#
-# == Overview
-#
-# This file provides two classes for working with
-# dates and times.
-#
-# The first class, Date, represents dates.
-# It works with years, months, weeks, and days.
-# See the Date class documentation for more details.
-#
-# The second, DateTime, extends Date to include hours,
-# minutes, seconds, and fractions of a second. It
-# provides basic support for time zones. See the
-# DateTime class documentation for more details.
-#
-# === Ways of calculating the date.
-#
-# In common usage, the date is reckoned in years since or
-# before the Common Era (CE/BCE, also known as AD/BC), then
-# as a month and day-of-the-month within the current year.
-# This is known as the *Civil* *Date*, and abbreviated
-# as +civil+ in the Date class.
-#
-# Instead of year, month-of-the-year, and day-of-the-month,
-# the date can also be reckoned in terms of year and
-# day-of-the-year. This is known as the *Ordinal* *Date*,
-# and is abbreviated as +ordinal+ in the Date class. (Note
-# that referring to this as the Julian date is incorrect.)
-#
-# The date can also be reckoned in terms of year, week-of-the-year,
-# and day-of-the-week. This is known as the *Commercial*
-# *Date*, and is abbreviated as +commercial+ in the
-# Date class. The commercial week runs Monday (day-of-the-week
-# 1) to Sunday (day-of-the-week 7), in contrast to the civil
-# week which runs Sunday (day-of-the-week 0) to Saturday
-# (day-of-the-week 6). The first week of the commercial year
-# starts on the Monday on or before January 1, and the commercial
-# year itself starts on this Monday, not January 1.
-#
-# For scientific purposes, it is convenient to refer to a date
-# simply as a day count, counting from an arbitrary initial
-# day. The date first chosen for this was January 1, 4713 BCE.
-# A count of days from this date is the *Julian* *Day* *Number*
-# or *Julian* *Date*, which is abbreviated as +jd+ in the
-# Date class. This is in local time, and counts from midnight
-# on the initial day. The stricter usage is in UTC, and counts
-# from midday on the initial day. This is referred to in the
-# Date class as the *Astronomical* *Julian* *Day* *Number*, and
-# abbreviated as +ajd+. In the Date class, the Astronomical
-# Julian Day Number includes fractional days.
-#
-# Another absolute day count is the *Modified* *Julian* *Day*
-# *Number*, which takes November 17, 1858 as its initial day.
-# This is abbreviated as +mjd+ in the Date class. There
-# is also an *Astronomical* *Modified* *Julian* *Day* *Number*,
-# which is in UTC and includes fractional days. This is
-# abbreviated as +amjd+ in the Date class. Like the Modified
-# Julian Day Number (and unlike the Astronomical Julian
-# Day Number), it counts from midnight.
-#
-# Alternative calendars such as the Ethiopic Solar Calendar,
-# the Islamic Lunar Calendar, or the French Revolutionary Calendar
-# are not supported by the Date class; nor are calendars that
-# are based on an Era different from the Common Era, such as
-# the Japanese Era.
-#
-# === Calendar Reform
-#
-# The standard civil year is 365 days long. However, the
-# solar year is fractionally longer than this. To account
-# for this, a *leap* *year* is occasionally inserted. This
-# is a year with 366 days, the extra day falling on February 29.
-# In the early days of the civil calendar, every fourth
-# year without exception was a leap year. This way of
-# reckoning leap years is the *Julian* *Calendar*.
-#
-# However, the solar year is marginally shorter than 365 1/4
-# days, and so the *Julian* *Calendar* gradually ran slow
-# over the centuries. To correct this, every 100th year
-# (but not every 400th year) was excluded as a leap year.
-# This way of reckoning leap years, which we use today, is
-# the *Gregorian* *Calendar*.
-#
-# The Gregorian Calendar was introduced at different times
-# in different regions. The day on which it was introduced
-# for a particular region is the *Day* *of* *Calendar*
-# *Reform* for that region. This is abbreviated as +sg+
-# (for Start of Gregorian calendar) in the Date class.
-#
-# Two such days are of particular
-# significance. The first is October 15, 1582, which was
-# the Day of Calendar Reform for Italy and most Catholic
-# countries. The second is September 14, 1752, which was
-# the Day of Calendar Reform for England and its colonies
-# (including what is now the United States). These two
-# dates are available as the constants Date::ITALY and
-# Date::ENGLAND, respectively. (By comparison, Germany and
-# Holland, less Catholic than Italy but less stubborn than
-# England, changed over in 1698; Sweden in 1753; Russia not
-# till 1918, after the Revolution; and Greece in 1923. Many
-# Orthodox churches still use the Julian Calendar. A complete
-# list of Days of Calendar Reform can be found at
-# http://www.polysyllabic.com/GregConv.html.)
-#
-# Switching from the Julian to the Gregorian calendar
-# involved skipping a number of days to make up for the
-# accumulated lag, and the later the switch was (or is)
-# done, the more days need to be skipped. So in 1582 in Italy,
-# 4th October was followed by 15th October, skipping 10 days; in 1752
-# in England, 2nd September was followed by 14th September, skipping
-# 11 days; and if I decided to switch from Julian to Gregorian
-# Calendar this midnight, I would go from 27th July 2003 (Julian)
-# today to 10th August 2003 (Gregorian) tomorrow, skipping
-# 13 days. The Date class is aware of this gap, and a supposed
-# date that would fall in the middle of it is regarded as invalid.
-#
-# The Day of Calendar Reform is relevant to all date representations
-# involving years. It is not relevant to the Julian Day Numbers,
-# except for converting between them and year-based representations.
-#
-# In the Date and DateTime classes, the Day of Calendar Reform or
-# +sg+ can be specified a number of ways. First, it can be as
-# the Julian Day Number of the Day of Calendar Reform. Second,
-# it can be using the constants Date::ITALY or Date::ENGLAND; these
-# are in fact the Julian Day Numbers of the Day of Calendar Reform
-# of the respective regions. Third, it can be as the constant
-# Date::JULIAN, which means to always use the Julian Calendar.
-# Finally, it can be as the constant Date::GREGORIAN, which means
-# to always use the Gregorian Calendar.
-#
-# Note: in the Julian Calendar, New Years Day was March 25. The
-# Date class does not follow this convention.
-#
-# === Offsets
-#
-# DateTime objects support a simple representation
-# of offsets. Offsets are represented as an offset
-# from UTC (UTC is not identical GMT; GMT is a historical term),
-# as a fraction of a day. This offset is the
-# how much local time is later (or earlier) than UTC.
-# As you travel east, the offset increases until you
-# reach the dateline in the middle of the Pacific Ocean;
-# as you travel west, the offset decreases. This offset
-# is abbreviated as +of+ in the Date class.
-#
-# This simple representation of offsets does not take
-# into account the common practice of Daylight Savings
-# Time or Summer Time.
-#
-# Most DateTime methods return the date and the
-# time in local time. The two exceptions are
-# #ajd() and #amjd(), which return the date and time
-# in UTC time, including fractional days.
-#
-# The Date class does not support offsets, in that
-# there is no way to create a Date object with non-utc offset.
-#
-# == Examples of use
-#
-# === Print out the date of every Sunday between two dates.
-#
-# def print_sundays(d1, d2)
-# d1 += 1 until d1.sunday?
-# d1.step(d2, 7) do |d|
-# puts d.strftime('%B %-d')
-# end
-# end
-#
-# print_sundays(Date.new(2003, 4, 8), Date.new(2003, 5, 23))
-
-require 'date/format'
-
-# Class representing a date.
-#
-# See the documentation to the file date.rb for an overview.
-#
-# Internally, the date is represented as an Astronomical
-# Julian Day Number, +ajd+. The Day of Calendar Reform, +sg+, is
-# also stored, for conversions to other date formats. (There
-# is also an +of+ field for a time zone offset, but this
-# is only for the use of the DateTime subclass.)
-#
-# A new Date object is created using one of the object creation
-# class methods named after the corresponding date format, and the
-# arguments appropriate to that date format; for instance,
-# Date::civil() (aliased to Date::new()) with year, month,
-# and day-of-month, or Date::ordinal() with year and day-of-year.
-# All of these object creation class methods also take the
-# Day of Calendar Reform as an optional argument.
-#
-# Date objects are immutable once created.
-#
-# Once a Date has been created, date values
-# can be retrieved for the different date formats supported
-# using instance methods. For instance, #mon() gives the
-# Civil month, #cwday() gives the Commercial day of the week,
-# and #yday() gives the Ordinal day of the year. Date values
-# can be retrieved in any format, regardless of what format
-# was used to create the Date instance.
-#
-# The Date class includes the Comparable module, allowing
-# date objects to be compared and sorted, ranges of dates
-# to be created, and so forth.
