[Answer] Which man was born on the same exact day as Abraham Lincoln?

Step 1 : Introduction to the question "Which man was born on the same exact day as Abraham Lincoln?"

...How's this for a coincidence? Abraham Lincoln and Charles Darwin were born on the same day, February 12, 1809. Lincoln and Darwin share similarities beyond their birthday and epic beards. Both lost their mothers at a young age: Darwin at 8 and Lincoln at 9. One was born in a log cabin in Kentucky to poor parents, the other in a country estate to a wealthy British family. The two never met. But they both changed the most basic ways that people viewed human existence and helped bring about a new era in the history of human thought.

[Answer] Which two U.S. states do not observe Daylight Saving Time?

Step 1 : Introduction to the question "Which two U.S. states do not observe Daylight Saving Time?"

...Most of the nation "sprang forward" and lost an hour of sleep switching to daylight saving time. Arizona and Hawaii did not. Hawaii opts out because its tropical location near the equator results in little seasonal change in daylight hours. Arizona remains on standard time year-round because the extra evening sunlight during summer months would increase energy use for air conditioning. The Navajo Nation in northeastern Arizona however, does observe Daylight Saving Time, creating an unusual situation where parts of the state follow different clocks.

Even today, the pyramid remains remarkably imposing: at 449.5 feet tall, standing taller than Big Ben, the Statue of Liberty, and the Leaning Tower of Pisa.
