How to read a May 31 Sun sign

Enter the birth year, local clock time, and a named time zone such as America/Los_Angeles. The named zone accounts for daylight saving rules on the birth date.
This lookup uses the tropical zodiac and identifies only the Sun sign. Use the chart step for other placements.
