Handover of perpetual calendar without festivals
What is a perpetual calendar
A monthly calendar that can be used to check the solar calendar, lunar calendar, and zodiac signs

What is seasonal handover?
That is to say, the years and months of the stems and branches are divided by solar terms, that is, the beginning of spring is regarded as the new year, and each even-numbered solar term is regarded as the new January. The handover without festivals means that the lunar month directly corresponds to the stems and branches of the moon pillar, and the first day of the first lunar month is regarded as the new year and the new year pillar. This calendar uses seasonal handover and uses https://github.com/6tail/lunar-typescript to calculate the lunar calendar and stems and branches (only the monthly stems and branches are calculated by ourselves)
