What do you mean by auspicious day and five elements?

Fire in the furnace: it means that the day is "Bing Yin" or "Ding Mao", and it can be considered that there is fire in the main branch of the day.

Description:

Sixty Jiazi's "Yin Na" is modeled after the sixty methods of ancient music, and the method is the same as that of the Book of Changes.

Bing Yin and Ding Mao's five elements are both "fires in the furnace", which have no good or bad luck in themselves, and need to be inferred from the relationship between birth and grams of other branches.

Bing Yin, brilliant fire. Without water, there will be heat, and water can't pass. I love the water of Jiayin alone, helping it to reach its place, also known as Chao.

Ding Mao, the fire of Fu Ming. Weak qi should be born in wood, and it is fierce when it meets water.
