Challenge of not having a unified global calendar.

Explanation:

Different nations have different calendars according to their religion and cultures. Each country has its customs to follow with a holiday on that day for celebrations. By having a separate calendar, it creates problems when markets, business, and stock markets are close in a country when the rest of the world is working on that particular day. For tourists, it creates a problem when they are not aware of the national holidays of a country when they find historical sights and museums close. The unified global calendar helps businesses, tourists, and trade.

background

early european explorers to the americas likely experienced emotions including awe at the vast "new" environment, amazement at meeting "others," the thrill of the unknown, concern for personal safety, desire for personal reward, and longing for their homeland and those left behind. written and pictorial records attributed to europeans provide the bulk of the records of these early travels. impressions of natives as well as native impressions of europeans are frequently framed in the narratives of the explorers. examination of these records indicates the cautious and curious nature of first encounters.

significance

centuries of ignorance, prejudice, and opinions lacking evidence or scholarly research have tainted traditional views of the earliest meetings between native americans (first nations in canada) and europeans. students may come to recognize how the later period of continued exploration, settlement, and interaction was influenced by these early encounters from the st. lawrence river to georgia.
