Rising sign
The rising sign, or ascendant, is the zodiac sign on the eastern horizon at birth. It needs a birth time and place. It is not the same as a Sun sign.
The difference people actually mean
Sun and rising get searched together because they are easy to confuse. Your Sun sign comes from your birthday. Your rising sign, also called the ascendant, is whichever sign was climbing the eastern horizon at your exact birth minute and birthplace. It changes about once every two hours, and about one degree every four minutes.
That is why two people born on the same day can meet the world differently, and why a rising sign cannot be calculated from a date alone. 'Sun rising sign' and 'Sun and ascendant' are the same question: they are two different placements, and both belong on one chart.
What the ascendant does in the chart
The rising sign begins the first house and sets the sequence of the other eleven. It is the chart's starting point, not a mask you should discard. The planet that rules the rising sign — the chart ruler — is often a useful second key to how a life is steered.
Without a recorded birth time, the rising sign and the houses stay uncertain. You can still read the planets by sign. You should not pretend the houses are exact.
Calculate it properly
Enter a date, a time, and a place. If the time is unknown, say so — a chart that admits the gap is more honest than a chart that invents 12:00. Astro Codes flags an estimated time rather than silently inventing an ascendant.
