Is a lunar day the same as the Moon’s age?
No. On La Lune, a traditional lunar day is counted using the new moon and local moonrise. Moon age is the elapsed time since the exact new moon. A label such as “lunar day 19” therefore does not mean the Moon is exactly 19 days old.

How does La Lune count lunar days?
Day 1 starts at the new moon. The next local moonrise begins day 2, and later moonrises advance the count until the next new moon resets it. Some lunar days are much shorter than a civil day. A cycle can contain 29 or 30 numbered days.
Why does the number depend on my city?
Moonrise occurs at different times in different places. At high latitudes the Moon may not rise on a given civil date, so the simple expectation of one new lunar day every 24 hours does not apply. Select a city and read the stated transition time.
Is this the same as tithi?
No. The Hindu tithi system divides the Sun–Moon angular separation into intervals. It uses a different definition. Moon age, moonrise-based lunar days and tithis should not be treated as interchangeable translations.
What do the symbols and daily meanings mean?
They belong to an interpretive lunar-calendar tradition. They are optional prompts for reflection, not astronomical measurements or predictions of what will happen to you. Use the phase calendar if you simply want the Moon’s appearance and exact phase times.
