More Than 24 Time Zones If each time zone were 1 hour apart, there would be 24 in the world. However, the International Date Line (IDL) creates 3 more. Also, several time zones are only 30 or 45 minutes apart, increasing the total number of standard time zones even further. Arpita ma'am is right as per NCERT is concerned.. I hope u got my points.
