BaZi Calendar 1930–2050
Year, month, day and hour pillars, with the solar terms in Beijing time
A reference calendar for BaZi, the Four Pillars of Destiny. For each year from 1930 to 2050 it gives the year pillar and the moment of 立春 to the minute, the thirteen solar months that touch the year with the moments of their 節 and 中氣 in Beijing time, and the day pillar of every date, 44,195 days in all. Seven reference tables cover the sixty pillars, the hidden stems, the month and hour pillars, true solar time and the start of the Luck Pillars, and the opening chapter works through three births step by step.

THE CALENDAR AND YOUR FREE CHART
The free calculator adds what a printed table cannot know: the clock history of the birthplace, with its time zone and summer time, and its true solar time. Use the book to understand and to check.
AFTER THE PILLARS
The calendar and the Day Master Books
The calendar gives the four pillars and does not interpret them. The stem on top of the day pillar is the Day Master, the centre of the chart, and each of the ten Day Masters has its own book.
Questions
What time are the solar terms given in?
In Beijing standard time (UTC+8), rounded to the minute, without summer time. A solar term is one instant for the whole Earth, so a birth anywhere is compared with it once both are on the same clock. Chapter 1 shows how, with births in London, Sydney and Shanghai.
Can I use it for a birth outside China?
Yes. The year and month pillars depend on the instant of birth, converted to Beijing time. The day pillar follows the local date of birth, and the hour pillar the local clock time with any summer time removed. The book does not list the summer time rules of other countries; the free calculator applies the recorded clock history of the birthplace.
How exact are the times?
The moments of the solar terms are computed from the JPL DE440 ephemeris and printed to the minute. Tables built on other astronomical models can differ by a minute, so for a birth within a few minutes of a boundary, check the exact time of birth and the clock it was recorded in. Before publication every day pillar and every month pillar was checked against independent calculations, and the finished PDF was read back and compared.
Does the calendar interpret a chart?
No. It gives the four pillars and the moments that decide them, the hidden stems of the branches, and the rules for the direction and the starting age of the Luck Pillars. It does not predict events. The Day Master, the stem on top of the day pillar, is the subject of the Day Master Books.
What do I get?
A PDF of 276 pages and an EPUB, sent to your email right after payment, and the same book to read online in your browser. They open on computers, tablets, phones and e-readers. The year pages are tables, and they are easiest to use in the PDF on a computer or a tablet.
Can I give it as a gift?
Yes. Choose “Give as a gift”, enter the recipient’s email and the day it should arrive. We email them a link on that day and send you a confirmation.
Can I get a refund?
Yes, whenever something is wrong on our side: a file that does not open or arrives damaged, the wrong book, or a double charge is refunded in full. Because the book is delivered at once, the 14-day right of withdrawal for digital content ends when you confirm instant delivery at checkout; where the law of your country gives a wider right (for example 7 days in Brazil), that law applies. Just write to support@bazi.cards with your order number. The full terms are on the refund policy page.
This calendar is a reference for the classical Chinese system of BaZi. It gives the year, month, day and hour pillars as the system counts them. It does not predict events and is not medical, financial, legal or psychological advice.
