In the lunar cycle, a waning gibbous phase occurs after the full moon and before the last quarter moon. The lunar cycle is typically about 29.5 days long, and the phases can be divided as follows:
1. **New Moon** (Day 0)
2. **Waxing Crescent** (Days 1-6)
3. **First Quarter** (Day 7)
4. **Waxing Gibbous** (Days 8-13)
5. **Full Moon** (Day 14)
6. **Waning Gibbous** (Days 15-20)
7. **Last Quarter** (Day 21)
8. **Waning Crescent** (Days 22-28)
9. **New Moon** (Day 29, repeating the cycle)
Therefore, the waning gibbous phase occurs from about Day 15 to Day 20 in the lunar cycle.
