Detailed Description

The QDate class provides date functions.

A QDate object contains a calendar date, i.e. year, month, and day numbers, in the modern Western (Gregorian) calendar. It can read the current date from the system clock. It provides functions for comparing dates and for manipulating dates, e.g. by adding a number of days or months or years.

A QDate object is typically created either by giving the year, month and day numbers explicitly, or by using the static function currentDate(), which creates a QDate object containing the system clock's date. An explicit date can also be set using setYMD(). The fromString() function returns a QDate given a string and a date format which is used to interpret the date within the string.

The year(), month(), and day() functions provide access to the year, month, and day numbers. Also, dayOfWeek() and dayOfYear() functions are provided. The same information is provided in textual format by the toString(), shortDayName(), longDayName(), shortMonthName() and longMonthName() functions.

QDate provides a full set of operators to compare two QDate objects where smaller means earlier and larger means later.

You can increment (or decrement) a date by a given number of days using addDays(). Similarly you can use addMonths() and addYears(). The daysTo() function returns the number of days between two dates.

The daysInMonth() and daysInYear() functions return how many days there are in this date's month and year, respectively. The leapYear() function indicates whether this date is in a leap year.

Note that QDate should not be used for date calculations for dates prior to the introduction of the Gregorian calendar. This calendar was adopted by England from the 14th September 1752 (hence this is the earliest valid QDate), and subsequently by most other Western countries, until 1923.

The end of time is reached around the year 8000, by which time we expect Qt to be obsolete.

isNull(), isValid()

Definition at line 54 of file qdatetime.h.

Referenced by fromString(), and weekNumber().

QDate::QDate (  int  y,
int  m,
int  d
) 
 

Constructs a date with year y, month m and day d.

y must be in the range 1752..8000, m must be in the range 1..12, and d must be in the range 1..31.

Warning:
If y is in the range 0..99, it is interpreted as 1900..1999.

Returns the date as a string. The format parameter determines the format of the result string.

These expressions may be used:

Expression Output d the day as number without a leading zero (1-31) dd the day as number with a leading zero (01-31) ddd the abbreviated localized day name (e.g. 'Mon'..'Sun'). Uses QDate::shortDayName(). dddd the long localized day name (e.g. 'Monday'..'Sunday'). Uses QDate::longDayName(). M the month as number without a leading zero (1-12) MM the month as number with a leading zero (01-12) MMM the abbreviated localized month name (e.g. 'Jan'..'Dec'). Uses QDate::shortMonthName(). MMMM the long localized month name (e.g. 'January'..'December'). Uses QDate::longMonthName(). yy the year as two digit number (00-99) yyyy the year as four digit number (1752-8000)

All other input characters will be ignored.

Example format strings (assuming that the QDate is the 20th July 1969): Format Result dd.MM.yyyy 20.07.1969 ddd MMMM d yy Sun July 20 69

QString QDate::toString (  Qt::DateFormat  f = Qt::TextDate  )  const
 

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Returns the date as a string. The f parameter determines the format of the string.

If f is Qt::TextDate, the string format is "Sat May 20 1995" (using the shortDayName() and shortMonthName() functions to generate the string, so the day and month names are locale specific).

If f is Qt::ISODate, the string format corresponds to the ISO 8601 specification for representations of dates, which is YYYY-MM-DD where YYYY is the year, MM is the month of the year (between 01 and 12), and DD is the day of the month between 01 and 31.

If f is Qt::LocalDate, the string format depends on the locale settings of the system.

int QDate::weekNumber (  int *  yearNumber = 0  )  const
 

Returns the week number (1 to 53), and stores the year in yearNumber unless yearNumber is null (the default).

Returns 0 if the date is invalid.

In accordance with ISO 8601, weeks start on Monday and the first Thursday of a year is always in week 1 of that year. Most years have 52 weeks, but some have 53.

*yearNumber is not always the same as year(). For example, 1 January 2000 has week number 52 in the year 1999, and 31 December 2002 has week number 1 in the year 2003.
