Questions tagged [qdate]

A QDate is a class from the Qt toolkit which provides functions for working with dates.

A QDate object contains information about a calendar date (for example its year, month, and day numbers), and can read the current date from the system clock. It also provides functions for comparing, formatting and parsing dates, and can perform basic date calculations.

The official documentation can be found here.
