Subject: Static GK (General Knowledge)

Book: General Time Knowledge

Time format varies worldwide due to historical, cultural, and practical considerations. While much of Europe and Asia favor the 24-hour clock, North and South American countries often use the 12-hour AM/PM format. Economic ties, international travel, and technological advancements have led to some standardization, yet pockets of unique local practices persist. This diversity can cause confusion in scheduling international meetings, especially when daylight saving shifts are factored in. Knowing why these differences exist helps travelers and remote workers navigate global appointments with fewer mix-ups and missed calls.
