Just release it on the auspicious day of 20 15.

Release time: it can be used all year round, but it is best to use it on the birthday of those who ask for longevity, or in the alternate year of quitting the old year and welcoming the new year, or on the first day, fifteenth day, Buddha's birthday, or before hospitalization, surgery, serious illness, car accident and other accidents. It is best to choose sunny days, when the sunshine is the most abundant and the effect is the best. Try to avoid releasing at night. It can also be released in rainy days.
