Aries and Cancer compatibility
Aries and Cancer both have a cardinal quality, associated with taking initiative. Aries approaches a new situation through direct action. Cancer considers care and belonging. The disagreement can concern what needs attention first, even when both people want to improve the situation.

Aries's emphasis
Aries makes a preference explicit and begins testing it. An immediate proposal gives a concern a practical direction. Acting before discussing its effect on others can leave them outside the decision.

Cancer considers the familiar connections affected by a change. Protecting time together can help a new plan feel workable. A concern needs a clear request before another person can respond to it.

Two readings of the same moment
One person accepts an invitation for the weekend. The other had expected their usual quiet time together. The invitation offers something new, but the change also affects an existing expectation.
Make the difference specific
Name the expectation and decide which parts of the weekend remain shared. Agree on when future invitations need a conversation before either person accepts.
Both themes can belong to one person
An Aries Sun and Cancer Moon can belong to one person. A wish to act independently can coexist with comfort in familiar company. Read the Sun and Moon as different functions.
In a two-chart reading, keep each planet attached to its owner. A Sun-Moon contact compares personal direction with emotional needs. A Venus-Mars contact compares affection with initiative.
Read the planet contactsSquare signs do not guarantee a close square
A planet at 10° Aries and another at 12° Cancer have a smaller separation of 92°. Their square orb is 2° from the exact 90° angle.
At 1° Aries and 29° Cancer, the smaller separation is 118°. The 28° orb is outside Astriel's 5° synastry square limit.
That second example is 2° from a trine, which falls within Astriel's limit for that contact. The degrees can describe a different aspect from the one suggested by the sign names.
These are synthetic positions. The calculator checks actual degrees and birth-time uncertainty. Sign symbolism cannot establish attraction, consent or the future of a relationship.

The sign comparison follows the owner-supplied astrology reference's element and modality definitions and sign themes. Examples are original. Advice about discussing preferences is an illustration, not a finding about the people whose charts you enter.
Orb limits come from Astriel's calculation method. Symbolic interpretation is separate from calculated geometry.
