EVENTS NEXT MONTH (12):
Last Quarter - May 1 @ 07:27
A waning half-Moon is near the meridian (halfway across the sky) as the Sun rises.
New Moon - May 6 @ 23:21
The Moon is nearest the Sun in the sky and cannot be seen from the ground.
Holland Liberated - May 7 @ 01:00
On this day in 1945, Canada accepted the surrender of German forces in the Netherlands, after a months-long campaign to dislodge them. This effort sparked a close and enduring friendship between the two countries.
V-E Day - May 8 @ 01:00
Victory-in-Europe Day celebrates the 1945 surrender by Nazi Germany to the Allied Forces. This had followed a vicious battle for the city of Berlin, and came little more than a week after Adolph Hitler had taken his own life.
Manitoba and NWT Join Confederation - May 12 @ 01:00
Today marks 154 years since Manitoba and the North West Territories joined the Canadian Confederation in 1870.
First Quarter - May 15 @ 07:48
A waxing half-Moon is near the meridian (halfway across the sky) as the Sun sets.
Eruption of Mt. St. Helens - May 18 @ 01:00
On this day in 1980 (now 44 years ago), Mount Saint Helens, a beautiful, symmetrical stratovolcano cone often referred to as "the Fuji of the Northwest," erupted explosively after months of signs that it was waking up. The eruption was triggered by a huge landslide, and the mountain blew away its summit and the southern quadrant of its cone. In many areas, for the next couple of days, it was pitch-black from the clouds of volcanic dust. Huge lahars washed down many rivers, and the showpiece of the area, Spirit Lake, was drowned in boiling debris. The eruption was extensively covered by international media. Subsequent smaller eruptions carried ash up into Canada. The sound of the eruption was heard up to 320 kilometres away, including by the Author, as he delivered papers on southern Vancouver Island.
Victoria Day - May 20 @ 00:00
Canada takes a holiday on this date, in celebration of the life and accomplishments of Her Majesty, Queen Victoria (1819-05-24 - 1901.01.22).

On this date, in 2022, a derecho hit southern Ontario and Quebec, with winds up to 190 km/h and a number of tornadoes. Damage was widespread, with many trees down and the power grid severely damaged. The Author experienced this storm, and classed it alongside Post-Tropical Storm Blanche, in 1975.
Full Moon - May 23 @ 09:53
The Moon is most-opposite the Sun in the sky, rising as the sun sets.
Last Quarter - May 30 @ 13:12

Barrie Tornado - May 31 @ 01:00
