Waxing or waning can be confusing because both words describe change, but they move in opposite directions.
Waxing means something is increasing, growing, or becoming stronger. Waning means it is decreasing, fading, or becoming weaker.
You may see these words when reading about the moon, popularity, influence, power, energy, or public interest.
For example, the moon can be waxing as its visible light increases, while someone’s influence may be waning as it slowly declines.
Once you connect each word with its direction of change, the difference becomes much easier to remember.

Waxing vs. Waning in the Moon
The most familiar use of waxing and waning is in descriptions of the Moon’s phases.
During a waxing moon, the illuminated portion visible from Earth is increasing. During a waning moon, the visible illuminated portion is decreasing.
The lunar cycle includes several phases:
- New Moon
- Waxing Crescent
- First Quarter
- Waxing Gibbous
- Full Moon
- Waning Gibbous
- Third Quarter
- Waning Crescent
Waxing Moon
A waxing moon moves from the New Moon toward the Full Moon. More of the Moon’s illuminated side becomes visible each night.
For example:
The Moon is waxing, and the crescent is becoming larger.
Waning Moon
A waning moon moves from the Full Moon toward the New Moon. The visible illuminated portion gradually becomes smaller.
For example:
The Moon is waning, and the bright portion is getting smaller.
Importantly, waxing and waning describe the amount of the Moon’s illuminated portion visible from Earth, not the Moon physically becoming larger or smaller.

Incorrect idea: Waxing and waning both mean changing.
While both describe change, they describe opposite directions.

Waning = decreasing
Mistake 2: Using waning for growth
