Questions
Is Mercury always near my Sun sign?
Yes. Mercury is never more than one sign away from your Sun, so it is often in the same sign as your Sun or an adjacent one.
Do I need exact birth time for my Mercury sign?
No. Mercury stays in each sign for weeks at a time, so this calculator reads your Mercury sign from your birth date alone and tells you when that is certain. Only if Mercury changed sign on your birthday does your birth time decide it, and the calculator shows you the exact minute of the change.
