@sshastry_c@Vishwa_devaiah@drjyothi_kumar Even psychologically it affects. When it's too bright outside, people tend to wake up earlier, might as well adjust it a bit so that they are not waiting to start their work day. So, during summer the regular 2 am EST becomes 3 am EDT. The day starts early with the sun
@sshastry_c@Vishwa_devaiah@drjyothi_kumar Technically they need not adjust. If sun rises 2 in the morning, so what? But maybe in pre electrification era it probably mattered a lot.
@sshastry_c@Vishwa_devaiah@drjyothi_kumar To give and example, at ~ 45° N latitude where I am, in Winter the sun rises close to 8 am and sets before 4 pm. Whereas in summer, it can be before 3 am and sets after 9pm.
@sshastry_c@Vishwa_devaiah@drjyothi_kumar The term 'easier term' is a relative one. I can try but don't hold me to that.
The farther you go from the equator, in either directions, the greater is the swing in sunrise and sunset time. The extremes are towards the poles where you don't even see sun for 6 months straight.
