href="glib-Date-and-Time-Functions.html#GDate"><span class="type">GDate</span></a> data structure represents a day between January 1, Year 1,and sometime a few thousand years in the future (right now it will goto the year 65535 or so, but <a href="glib-Date-and-Time-Functions.html#g-date-set-parse"><code class="function">g_date_set_parse()</code></a> only parses up to theyear 8000 or so - just count on "a few thousand"). <a href="glib-Date-and-Time-Functions.html#GDate"><span class="type">GDate</span></a> is meant torepresent everyday dates, not astronomical dates or historical datesor ISO timestamps or the like. It extrapolates the current Gregoriancalendar forward and backward in time; there is no attempt to changethe calendar to match time periods or locations. <a href="glib-Date-and-Time-Functions.html#GDate"><span class="type">GDate</span></a> does not storetime information; it represents a <span class="emphasis"><em>day</em></span>.</p><p>The <a href="glib-Date-and-Time-Functions.html#GDate"><span class="type">GDate</span></a> implementation has several nice features; it is only a64-bit struct, so storing large numbers of dates is very efficient. Itcan keep both a Julian and day-month-year representation of the date,since some calculations are much easier with one representation or theother. A Julian representation is simply a count of days since somefixed day in the past; for <a href="glib-Date-and-Time-Functions.html#GDate"><span class="type">GDate</span></a> the fixed day is January 1, 1 AD.("Julian" dates in the <a href="glib-Date-and-Time-Functions.html#GDate"><span class="type">GDate</span></a> API aren't really Julian dates in thetechnical sense; technically, Julian dates count from the start of theJulian period, Jan 1, 4713 BC).</p><p><a href="glib-Date-and-Time-Functions.html#GDate"><span class="type">GDate</span></a> is simple to use. First you need a "blank" date; you can get adynamically allocated date from <a href="glib-Date-and-Time-Functions.html#g-date-new"><code class="function">g_date_new()</code></a>, or you can declare anautomatic variable or array and initialize it to a sane state bycalling <a href="glib-Date-and-Time-Functions.html#g-date-clear"><code class="function">g_date_clear()</code></a>. A cleared date is sane; it's safe to call<a href="glib-Date-and-Time-Functions.html#g-date-set-dmy"><code class="function">g_date_set_dmy()</code></a> and the other mutator functions to initialize thevalue of a cleared date. However, a cleared date is initially<span class="emphasis"><em>invalid</em></span>, meaning that it doesn't represent a daythat exists. It is undefined to call any of the date calculationroutines on an invalid date. If you obtain a date from a user or otherunpredictable source, you should check its validity with the<a href="glib-Date-and-Time-Functions.html#g-date-valid"><code class="function">g_date_valid()</code></a> predicate. <a href="glib-Date-and-Time-Functions.html#g-date-valid"><code class="function">g_date_valid()</code></a> is also used to check forerrors with <a href="glib-Date-and-Time-Functions.html#g-date-set-parse"><code class="function">g_date_set_parse()</code></a> and other functions that canfail. Dates can be invalidated by calling <a href="glib-Date-and-Time-Functions.html#g-date-clear"><code class="function">g_date_clear()</code></a> again.</p><p><span class="emphasis"><em>It is very important to use the API to access the <a href="glib-Date-and-Time-Functions.html#GDate"><span class="type">GDate</span></a>struct.</em></span> Often only the day-month-year or only the Julianrepresentation is valid. Sometimes neither is valid.
