What is a "Freeday"?

In Korean tradition, “freedays” (Son Eomneun Nal) are considered auspicious days for events like moving, opening a business, or holding weddings. These days are believed to be free from disruptive spirits, making them ideal for important tasks.

How is it calculated?

Freedays are fixed as the 9th, 10th, 19th, 20th, 29th, and 30th days of the lunar month. This calculator converts these lunar dates into solar dates using accurate lunar data.
