After that, days still get longer, but at an ever-decreasing rate. On the longest day of the year, the <a href="/calendar/summer-solstice.html">summer solstice</a>, the day-to-day difference reaches zero.</p><p>At the same time, locations farther from the equator experience larger day-to-day differences. In <a href="/sun/canada/toronto?month=3">Toronto</a>, the day of the spring equinox is 3 minutes longer than the previous day; in <a href="/sun/usa/miami?month=3">Miami</a>, roughly 2000 kilometers or 1200 miles farther south, the difference is only about 1 minute and 31 seconds.</p><p class=large-link><a href="/scripts/go.php?type=sun">Day-to-day differences in your city</a></p><figure class="article__figure article__figure--zoomable" data-tad-control=ClassOnClick data-tad-options="{classname: 'article__figure--zoomed'}"><div class=article__img-container><img src="//c.tadst.com/gfx/600x337/equinoxes-and-solstice.png?1" width=600 height=337 title="Equinox and solstice illustration." alt="Equinox and solstice illustration." class=article__img srcset="//c.tadst.com/gfx/900x506/equinoxes-and-solstice.png?1 1.5x,//c.tadst.com/gfx/1200x675/equinoxes-and-solstice.png?1 2x"></div><div class=article__lightbox><img src="//c.tadst.com/gfx/1200x675/equinoxes-and-solstice.png?1" width=1200 height=675 title="Equinox and solstice illustration." alt="Equinox and solstice illustration." class=article__img-large loading=lazy></div><figcaption><p class=article__img-caption>Our Earth is tilted as it orbits the Sun, which is the reason we have seasons on Earth.</p><p class=article__img-credit>©timeanddate.com</p></figcaption></figure><h2>Equal Day and Night?</h2><p>Astronomical spring begins on the day of the equinox. The name of the event derives from Latin and means <strong>equal night</strong>, giving the impression that both day and night are exactly 12 hours long. However, that is <strong>not entirely true</strong>. In most regions, daytime at the equinox is <a href="/astronomy/equinox-not-equal.html">a bit longer than 12 hours</a>.</p><h2>Equilux</h2><p>The date when <a href="/astronomy/equilux.html">day and night are <em>actually</em> equal</a> is called the equilux. It falls a few days <strong>before the spring equinox</strong> and some days <strong>after the fall equinox</strong> in both hemispheres.</p><p class=large-link><a href="/astronomy/explanation-terms.html">Other astronomical terms & definitions</a></p><h2>Rising Temperatures</h2><p>Particularly in the temperate zone, which is the region between the tropics and the polar regions, spring is also the time when the cold of <a href="/calendar/winter-solstice.html">winter</a> begins to give way to <strong>warmer weather</strong>, though this varies substantially from one region to another.</p><p class=large-link><a href="/scripts/go.php?type=climate">Climate and monthly average temperatures in your city</a></p><h2>Traditions and Folklore</h2><p>The start of spring and the spring equinox are celebrated in cultures and religions around the world with various <strong>spring traditions, holidays, and festivals</strong>.</p><p class=large-link><a href="/calendar/march-equinox-traditions.html">Easter, New Year, and the “other shore”: spring festivals of the world</a></p><h2>Spring Months</h2><p>In the Northern Hemisphere, depending on which definition you use, spring can include parts or all of the months of March, April, May, and June. South of the equator, it starts in September and ends in December.
