Poem of Months of the Year
Thirty days hath September,
April, June, and November;
All the rest have thirty-one,
Excepting February alone,
Which hath twenty-eight days clear,
And twenty-nine in each leap year.

● Season from National Geographic. Seasons are largely due to factors surrounding Earth's tilted axis as it revolves around the sun. In the Northern Hemisphere, winter generally begins on December 21 or 22. This is the winter solstice, the day of the year with the shortest period of daylight. Summer begins on June 20 or 21, the summer solstice, which has the most daylight of any day in the year. Spring and fall, or autumn, begin on equinoxes, days that have equal amounts of daylight and darkness. The vernal, or spring, equinox falls on March 20 or 21, and the autumnal equinox is on September 22 or 23. The seasons in the Northern Hemisphere are the opposite of those in the Southern Hemisphere.

● Daylight Savings Time: Why Do the Clocks Change? From University Canada West, 2023. Daylight Savings Time is a practice of adjusting the clock ahead by one hour during the summer months in order to maximize the use of daylight and conserve energy. Pros: The benefits of Daylight Savings Time include conserving energy by reducing the need for artificial lighting during the summer months, when there are more daylight hours. By setting the clock ahead one hour, people can take advantage of the extra daylight at night and reduce their use of electricity for lighting. Cons: Daylight Savings Time has been associated with several safety risks, particularly related to sleep disruption and changes in circadian rhythms. When the clocks are adjusted forward or backward by one hour, it can disrupt people's sleep patterns and lead to a temporary increase in fatigue, which can increase the risk of accidents and injuries.

Poem of Days of the Week
Monday's child is fair of face,
Tuesday's child is full of grace,
Wednesday's child is full of woe,
Thursday's child has far to go,
Friday's child is loving and giving,
Saturday's child works hard for a living,
But the child who is born on the Sabbath Day
Is bonny and blithe and good and gay.

● 12-hour clock from Wikipedia, the free encyclopedia. "In the United States ... noon is often called 12:00 p.m. and midnight 12:00 a.m., as at the beginning of a day. ... Strictly speaking, 12 A.M. denotes midnight, and 12 P.M. denotes noon, but there is sufficient confusion over these uses to make it advisable to use 12 noon and 12 midnight where clarity is required."
