What are the two phases during The moon appears as only a tiny silver?

The two phases during which the moon appears as only a tiny silver sliver are the Waxing Crescent and the Waning Crescent phases. In the Waxing Crescent phase, the moon is transitioning from new moon to first quarter, becoming more illuminated each night. In contrast, during the Waning Crescent phase, it is moving from the last quarter back to the new moon, with decreasing illumination. Both phases showcase a slim crescent shape, often appearing just before or after the new moon.
