366 calculated dates

Every birthday.
Actually computed.

Most sites print a date table. This one calculates the Sun's position on your date for every year from 1930 to 2035 and tells you what actually happened — including the twelve dates where the answer changes with the year, and the exact minute it changed.

Why a date is not an answer

The Sun does not move on a schedule the calendar keeps.

A tropical year is about 365.2422 days long, so the instant the Sun crosses into a sign drifts roughly six hours later each year and snaps back on the leap day. Over four years that is nearly a full day of movement — which is why two people born on the same date in different years can hold different sun signs, and why every date page here shows the calculation rather than a range.

The colour on each cell comes from the conventional date table, which is what the rest of the internet publishes. The calculated answer — and, on a boundary date, the year-by-year verdict — is on the date itself.

A date is one coordinate

Your Sun is one of about forty placements.

The Moon lands somewhere different on your date almost every year, and the rising sign changes every two hours. Both need a birth time and a place — which takes a minute to enter and settles all three at once.

Frequently asked questions

How is the sun sign for each date calculated?
For every date, MyMysticDay computes the Sun's apparent longitude at the start, middle and end of the day for each year from 1930 to 2035, then reports how often the date fell in each sign and the exact minute of any crossing. No date table is used.
Why do some dates have two possible signs?
The Sun crosses each sign boundary at a precise instant that drifts by nearly a day across the four-year leap cycle. On the twelve boundary dates the answer therefore depends on the birth year, and within a few hours of the crossing it also depends on the birth time and time zone.
Can these pages tell me my Moon sign or rising sign?
No, and each page shows why: the Moon lands in almost every sign on any given date across a century, and the rising sign changes roughly every two hours. Both need a birth time and place, which the free birth chart calculator asks for.
Which zodiac is used?
The tropical zodiac, measured from the March equinox, consistently across every calculator and interpretation on this site. Sidereal positions differ by roughly 24 degrees and are not mixed in.
