I am from India, northern part, where there is a lotbof variation between sunlight hours throughout the year. Some days the sun is out at 6 or before in summer, & in winter its some time not out even till 9 or such. India does not use timezones. Every business, school, office who has business hours, use something like Winter Timings Summer Timings. Schools & such use 14 Oct to 14 Apr as Winter, & other 6 months as summer. My school used to open at 6 in summers, & 7:30 or 8 in winters. Here in US they keep the opening timings same throughout the year, but go through this DST shenanigans.
