No. The phase has an exact time, but the Moon’s shape changes gradually. Near a quarter, it looks half-lit for about a day on either side, and a crescent grows or shrinks only a little from one night to the next.
The Full Moon happens at one moment worldwide, but local clocks put it on different dates. For example, the Full Moon of December 13 in New York falls on December 14 in Sydney.
The Full Moon of December 13 is traditionally called the Cold Moon. These names come from North American tradition and follow Northern Hemisphere seasons, so in the Southern Hemisphere they don’t match the season.
