Pt::Date is an easy way to handle calendar dates. It can be constructed from the days, month and year components or from an ISO string using fromIsoString(). The date components can be accessed with day(), month() and year(). Once a Date object is created, calendar information can be accessed, for example with dayOfYear(), dayOfWeek() or isLeapYear(). Dates can be compared and a Date is considered less if it is earlier than another Date. It is also possible to add or subtract days from a Date, which yields a new date or modifies it. Dates can be subtracted, which yields the number of days between them, as shown in the next example:
#include <Pt/Date.h>
#include <iostream>
int daysUntilChristmas(const std::string& todayStr)
{
return xmas - today;
}
Pt::InvalidDate is thrown, if a date could not be constructed, for example if one of the date components is out of range. To avoid an exception, date components can be validated with isValid().
