Who Invented Time? The Strange Story Behind 24 Hours, 60 Minutes & Our Calendar | Part 1 | Hindi

Who decided that a day has 24 hours? Why are there 60 minutes in an hour? And who decided what a “day” or a “month” actually means? We use time every single day—but almost never stop to ask where it came from. Thousands of years ago, there were no clocks, no January, no Monday, and no year called 2026. Humans had only the Sun, Moon, stars and changing seasons. So how did they turn those natural cycles into the system of time we use today? In this episode, we go back thousands of years to uncover the story behind: 🌙 The Moon and the first calendars ☀️ The Egyptian 365-day year 🏺 How ancient Egyptians divided the day 🕛 Why we have 24 hours 🔢 Why 60 became so important 📐 Ancient Mesopotamian mathematics ⏱️ The origins of minutes and seconds 📅 Why calendars don’t perfectly match the seasons 🌌 How humans turned the sky into mathematics And this is only the beginning. CHAPTER 1 — BEFORE CLOCKS: HUMANS READ THE SKY : 2:20 - 4:29 CHAPTER 2 — THE MOON, MONTHS & THE FIRST CALENDARS : 4:30 - 6:50 CHAPTER 3 — THE SUN, SEASONS & THE 365-DAY YEAR : 6:51 - 8:53 CHAPTER 4 — ANCIENT EGYPT: HOW THE DAY BECAME 24 HOURS : 8:54 - 10:55 CHAPTER 5 — WHY 60 MINUTES & 60 SECONDS? : 10:56 - 13:00 Because after humans learned to read time, they faced a much harder problem: How could they actually measure it? What happened when the Sun disappeared? How could someone measure an hour at night? How did humans build the first machines that could keep time? And how did those primitive devices eventually lead to the clocks we carry in our pockets today? That’s where the next chapter of the story begins. Part 2: When Humans Built Time — Coming Next.
