More from the article:

The Purim supermoon will be the final in a series of three consecutive full-moon/ supermoons. The next appearance of supermoons will also be a triad, culminating on the night before Rosh Hashanah (the Jewish New Year).

Purim also coincides with the vernal (spring) equinox when the Sun crosses the celestial equator – the imaginary line in the sky above the Earth’s equator – from south to north. On the equinox, the day and night are each about 12 hours in length everywhere on Earth.

The previous super moon was on my birthday ^^
