seven-day candle

A seven-day candle is a tall, cylindrical candle in a glass container designed to burn continuously for about a week.

Common in Catholic devotional practice, they're lit for prayer intentions, memorials, or to honor saints—often bearing religious imagery on the glass.

They also appear in folk magic traditions like hoodoo and santería, where different colors correspond to different purposes: She lit a green seven-day candle for prosperity.
