Once in a blue Moon
We have all heard the term once in a blue moon and as a matter of interest here in the southern hemisphere we will have our second full moon for the month on the 30th of June. Making this month a blue moon month. You see a blue moon is more unusual because it requires two full moons in one calendar month for them to occur, and there for they only occur every two to three years. So we only have blue moons occasionally and this year depending on where you live it will occur in either May or June or July. Ours here in Australia will occur in June as we had our 1st full moon on the 1st of the month and the second will be on the 30th of the month.
Blue moons donât necessarily mean that the moon is blue however the moon has been known to look blue sometimes. To have two blue moons (double blue moons) in a year only happens about four or five times in a hundred years.
Something else happening on June the 21st. 22nd here in the Southern Hemisphere is the Winter Solstice and that means we have our shortest day of the year, meaning between sunrise and sunset in actual daylight time.
