typedef ymd_type::month_type boost::date_time::gregorian_calendar_base< greg_year_month_day , fancy_date_rep::int_type >::month_type

inherited

define a type for representing months

typedef ymd_type::year_type boost::date_time::gregorian_calendar_base< greg_year_month_day , fancy_date_rep::int_type >::year_type

inherited

Type to hold a stand alone year value (eg: 2002)

typedef greg_year_month_day boost::date_time::gregorian_calendar_base< greg_year_month_day , fancy_date_rep::int_type >::ymd_type

inherited

define a type a date split into components

Member Function Documentation

static date_int_type boost::date_time::gregorian_calendar_base< greg_year_month_day , fancy_date_rep::int_type >::day_number ( const ymd_type & ymd )

staticinherited

Convert a ymd_type into a day number.

The day number is an absolute number of days since the start of count

static unsigned short boost::date_time::gregorian_calendar_base< greg_year_month_day , fancy_date_rep::int_type >::day_of_week ( const ymd_type & ymd )

staticinherited

Return the day of the week (0==Sunday, 1==Monday, etc)

Converts a year-month-day into a day of the week number

static unsigned short boost::date_time::gregorian_calendar_base< greg_year_month_day , fancy_date_rep::int_type >::days_in_week ( )

staticinherited

Defines length of a week for week calculations.

static unsigned short boost::date_time::gregorian_calendar_base< greg_year_month_day , fancy_date_rep::int_type >::end_of_month_day	(	year_type	y,
		month_type	m
	)

staticinherited

Calculate the last day of the month.

Find the day which is the end of the month given year and month No error checking is performed.

static ymd_type boost::date_time::gregorian_calendar_base< greg_year_month_day , fancy_date_rep::int_type >::epoch ( )

staticinherited

Provide the ymd_type specification for the calandar start.

static ymd_type boost::date_time::gregorian_calendar_base< greg_year_month_day , fancy_date_rep::int_type >::from_day_number ( date_int_type )

staticinherited

Change a day number into a year-month-day.

static ymd_type boost::date_time::gregorian_calendar_base< greg_year_month_day , fancy_date_rep::int_type >::from_julian_day_number ( date_int_type )

staticinherited

Change a day number into a year-month-day.

static ymd_type boost::date_time::gregorian_calendar_base< greg_year_month_day , fancy_date_rep::int_type >::from_modjulian_day_number ( date_int_type )

staticinherited

Change a modified julian day number into a year-month-day.

static bool boost::date_time::gregorian_calendar_base< greg_year_month_day , fancy_date_rep::int_type >::is_leap_year ( year_type )

staticinherited

Determine if the provided year is a leap year.

Returns: true if year is a leap year, false otherwise

static date_int_type boost::date_time::gregorian_calendar_base< greg_year_month_day , fancy_date_rep::int_type >::julian_day_number ( const ymd_type & ymd )

staticinherited

Convert a year-month-day into the julian day number.

Since this implementation uses julian day internally, this is the same as the day_number.

static date_int_type boost::date_time::gregorian_calendar_base< greg_year_month_day , fancy_date_rep::int_type >::modjulian_day_number ( const ymd_type & ymd )

staticinherited

Convert year-month-day into a modified julian day number.

The day number is an absolute number of days. MJD 0 thus started on 17 Nov 1858(Gregorian) at 00:00:00 UTC

static int boost::date_time::gregorian_calendar_base< greg_year_month_day , fancy_date_rep::int_type >::week_number ( const ymd_type & ymd )

staticinherited

Return the iso week number for the date.

Implements the rules associated with the iso 8601 week number. Basically the rule is that Week 1 of the year is the week that contains January 4th or the week that contains the first Thursday in January. Reference for this algorithm is the Calendar FAQ by Claus Tondering, April 2000.
