Your birthday is the day a new year's chart opens up.
The sky turns and turns, and there's a moment it comes back to its original spot. The method of drawing a new chart for that moment's sky and reading the theme of the coming year or month is called a return chart.
A Solar Return is a chart drawn for the sky at the moment the Sun returns exactly to the spot it was at your birth, in other words, around your birthday. That single chart is thought to tell you the big theme for that year. A birthday isn't just a day you add a year — it's really the day a new year's chart opens up.
A Lunar Return is the moment the Moon returns to the spot it was at your birth. The Moon moves fast, so it comes around about every 27 days, meaning about once a month. It's used for tracking each month's emotional flow and inner rhythm.
Drawing a return chart exactly means recalculating the sky for that exact moment, an advanced technique — so here the goal is just grasping the concept. Instead, Glowy tracks the flow the 'sky right now' gives you for you every day.
