the sun rise two hours eariel in arunachal pradesh as compard to gujarat
Answers
●The sun rises 2 hours earlier in Arunachal Pradesh compared to Gujarat but the clock shows the same time because the time along the standard meridian of India passing through Mirzapur, Uttar Pradesh is taken as the standard time for the whole country.
The watches show the same time because:
The whole of the India operates to a single time zone i.e India Standard Time ( IST ). It is 5:30 hours (5 hours 30 minutes) ahead of Greenwich mean time(GMT+5.5). It is calculated on the basis of 82.30' E longitude which passes through Allahabad. So, officially there is no time lag between Arunachal Pradesh and Gujarat.
But yes, sun rises 2 hours earlier in Arunachal Pradesh in compare to Gujarat because:
Gujarat lies between 68° E and 74° E longitude and whereas, Arunachal Pradesh is located between 91.20° E and 97.30° E longitude. So, approximately both the states have 29 degree longitude difference in term of location. The time difference between each degree of longitude is 4 minutes and If we go eastward, the local time is advance by 4 minutes with each additional degree and vice versa. As, Arunachal Pradesh lies on eastern side, it will have an advance local time {29 × 4 = 116 (approximately 2 hours}. Therefore, Arunachal Pradesh is 2 hours ahead of Gujarat in term of local time.
