Ten days into December, the Mars decan of Sagittarius is in its late stretch, and the birthdays here get its most durable cut. The stereotype says fire signs sprint and fade. December 10 is the counterexample: heat that holds, enthusiasm with a maintenance schedule, an Archer built for the marathon as much as the launch.
Stamina, not just spark
A Sagittarius Sun supplies the ignition; this decan’s Mars keeps feeding the flame. December 10 people finish the degree while employed, train through the winter, stay curious about a subject long after the novelty has worn off. Their optimism is less fireworks than furnace — steady output, low drama, surprising totals. People underestimate them at the start of long efforts and have stopped by the middle.
The long haul, together
In love, this is the fire sign you can actually build with. The courtship may start fast — it usually does — but what distinguishes December 10 is year seven: still planning trips, still asking real questions, still amused. It wants a partner for the whole route, not just the scenic parts, and it notices who packs for weather. At work, hand it the long project everyone fears — the migration, the multi-year study, the rebuild — then check in occasionally. It neither needs nor wants a cheering section.
Learning to idle
The friction is that the engine never quite gets switched off. December 10 treats rest as a pit stop: grudging, brief, scheduled around the next leg. Burnout does not announce itself in a temperament like this — it just arrives as flatness where the appetite used to be. The growth edge is idling with no finish line in sight, and trusting the fire to relight. It always has.
Distance suits the Sun sign; pace and terrain are set by the rest of the chart. Birth time and place turn this date into your actual sky — the birth chart calculator does the computing.
