2. See also Date & Time: Lunar phase: Current.

3. For (lunar fractional) illumination, see USNO Table 2026: lunar fractional illumination. The table can be updated for the current year by updating the URL or by computing a new table from USNO: Fraction of the Moon Illuminated.

   

4. Image 2 Caption: A plot of illumination as a function of the Moon's age (i.e., the day count of the lunar month). The current Moon's age and illumination for the current lunar month is given at NASA: Daily Moon Guide.

   Day count 0 and day count 29.5 are both new moon. Recall, the lunar month = 29.530588861 days (J2000) ≅ 29.53059 days (mean J2000 to 7 digits) ≅ 29.5 days.

   For a similar plot, see Britannica Kids: Visible fraction of the Moon's near side illuminated over 64 days.
