Ishaan apne parivaar par project bana raha hai. Wo ek lambi rekha kheenchta aur nishaan lagata hai: 1958 Daadi ka janm, 1985 Papa ka janm, 2014 Ishaan ka janm. "Ab poori kahaani ek nazar mein dikhti hai!" wo kehta hai. Usne samay rekha (timeline) banaai hai.

Itihaaskaar samay bade hisson mein naapte hain: dashak 10 saal, shataabdi 100 saal, aur sahasraabdi 1,000 saal. Saal 1901 se 2000 20vi shataabdi hain; hum ab 21vi shataabdi (2001–2100) mein hain.

Aaj zyaadatar duniya saal ek shuruaati bindu se ginti hai jise Common Era (CE) ki shuruaat kehte hain. Usse pehle ke saal BCE (Before Common Era) hain aur ulte gine jaate hain: 300 BCE, 200 BCE se pehle aaya. Saal 0 nahi hota: 1 BCE ke baad seedha 1 CE.

Bhaarat ke apne calendar bhi hain, jaise Vikram Samvat aur Shaka Samvat (raashtriya calendar). Alag calendar alag ghatnaon se ginti shuru karte hain, par samay rekha sabko ek rekha par rakh deti hai.

Explore: samay rekha par chalo.

  1. Marker 1500 BCE par rakho.
  2. Ab 500 CE par.
  3. Ise 500 CE se 1,000 saal pehle rakho.

Yaad rakho

  • Samay rekha ghatnaayein kram mein dikhaati hai; dashak 10 saal, shataabdi 100, sahasraabdi 1,000.
  • BCE saal CE ki taraf ulte gine jaate hain; saal 0 nahi hota.

Quick check

Pehle kya aaya: 400 BCE ya 100 BCE?

  1. 400 BCE
  2. 100 BCE
  3. Same saal hai
  4. Pata nahi chal sakta
Answer

400 BCE. BCE saal ulte gine jaate hain, to bada number pehle hai.

Socho

Ek bartan 200 BCE mein bana aur 2000 CE mein mila. Milne par kitna purana tha?

Ek answer

200 + 2000 − 1 = 2,199 saal (1 ghatate hain kyunki saal 0 nahi). Itihaaskaar aksar bas kehte hain "lagbhag 2,200 saal purana".
