In order to obtain an accurate astrological chart, the date,
time of birth and the city of the birth are needed in order to do a complete chart calculation.
How to adjust the time of birth to use the planet calculator.
Most individuals are not born in the timezone of Greenwich Mean Time (GMT). So, to adjust the birthtime, it is important to know which timezone you were born in. For our example, we will pick a birth time but use different places.
Let's say a person was born on March 22, 1943 at 5:30 a.m. We will need to adjust that time based on GMT. Without the location, we can't get the correct time. It is important to know the timezone to adjust the birthtime to GMT.
For example, March 22, 1943 at 5:30 a.m. Pacific Standard Time (PST) +8 hours would adjust to March 22, 1943 13:30 GMT while March 22, 1943 5:30 a.m. China Coast Time (CCT) -8 hours would adjust to March 21 1943 21:30 GMT. Notice that the "day" and "time" may both change due of the adjustment for the timezone.
The table below gives you a sense of how important it is to find the right time for GMT. The Moon's sign and placement based on the timezone adjusted birthtime can change both by degree and by sign.
