Each day's verdict follows the traditional Dong Gong date-selection system and the twelve Day Officers, with activity guidance published as 宜, 忌 or neutral.
Precise solar terms
Solar-term moments are calculated from astronomical data covering 1900 to 2101, and the table is checked against its checksum every time it loads. Births close to a boundary are flagged, never guessed.
The same answer every time
The same details and the same method version always give the same result. Nothing is improvised.
No. The Tong Shu is a traditional Chinese almanac that people have used for centuries to plan important days. MyTongShu calculates it precisely and reads it against your BaZi birth chart. It's guidance for planning, not a prediction or a guarantee.
What if I don't know my birth time?
That's fine. Choose "I don't know my birth time" and we'll read your day from your birth date and birthplace. Adding the time later gives a fuller reading.
Do you store my birth details?
Free preview details are used for that one reading and aren't saved to an account. If you choose Personal, your birth details are encrypted, tied to your account, and never shared or used for advertising.
How does renewal work?
Your plan renews once a year at the price shown when you buy. You can turn off auto-renewal anytime in Account and keep access until the end of the 12 months you paid for, counted from the day you join.
Can I get a refund?
Ordinary subscription payments aren't refunded, which is why we show you a free personal preview first. Turning off auto-renewal stops all future charges. Duplicate or unauthorised charges are handled under our refund policy, and your statutory rights are unaffected.
General or Personal?
General is the full almanac for every day of the year, and it doesn't need birth details. Personal includes everything in General, plus every day read against your own BaZi chart.
