What is true solar time and does it change my chart?

True solar time is the time a sundial at your birthplace would show. It differs from clock time due to your longitude within the time zone (four minutes per degree from the standard meridian) and the equation of time, an annual wobble of roughly −14 to +16 minutes. Together the correction often exceeds half an hour, which is enough to move a birth into a different traditional hour — and near midnight, a different day. The calculator applies both corrections automatically and warns when the correction changes a pillar.

What is true solar time, and does it change my chart?

True solar time is the time a sundial at your birthplace would show. It differs from clock time for two reasons: your longitude within the time zone (four minutes per degree from the standard meridian) and the equation of time, an annual wobble of roughly −14 to +16 minutes. Together the correction often exceeds half an hour, which is enough to move a birth into a different traditional hour — and near midnight, a different day. This calculator applies both corrections automatically from your birthplace, and warns you when the correction changes a pillar.

I was born during daylight saving time. Do I need to adjust my birth time?

No — enter the clock time exactly as recorded, and the engine handles the rest. It carries historical daylight saving rules for 124 countries and regions, including cases most tools miss: China observed summer time only from 1986 to 1991 with different dates each year, and several countries had wartime or transitional rules that no simple formula captures. When your birth falls in a DST window, the calculator flags it and applies the correction visibly.
