THE SHORT ANSWER
Use the birth details you know. An hour can be enough to get started; if the time is unknown, use the tool’s unknown-time option where available and read the notes about what is missing.

You may still be able to begin.
Not everyone has a recorded birth time. Your birth year, month, and day still give you parts of a chart to explore, even when the hour is missing.
Joy Luck’s personal chart and romantic relationship compatibility reading let you begin without a known time and explain what that leaves out. You can explore strengths and differences with the details you have, while keeping room for what a birth hour might add.
What does the hour add?
Your birth hour adds a fourth pillar, with another element and animal symbol. It can change the element mix and bring in animal relationships that are not visible in a chart made without it.
Timing can matter more near the change of a day or a seasonal boundary. In a relationship reading, an unknown time for either person also leaves part of the comparison open. Follow the notes for the particular report you are creating.
| What you know | Where to begin |
|---|---|
| Birth date and birthplace | Enter those details and read the missing-time notes. |
| The hour, but not the exact minute | Use the hour you know. Check any uncertainty notes, especially near a chart boundary. |
| A broad time, such as “morning” | If you cannot narrow it to an hour, use the unknown-time option where available. |
| No birth time | Leave it blank or choose the unknown-time option when the report allows it. |
| You later find a reliable recorded time | Create your chart again to see what the added information changes. |
It’s okay to leave it unknown.
It can be tempting to enter noon just to fill the box. But that gives the calculator a specific hour to work with, even though you do not know whether it is right.
The same goes for choosing a time because its description sounds like you. A familiar description cannot confirm your birth time. A recorded time, a family estimate, and an unknown time each deserve a different level of confidence.
Keep the details simple.
Enter the date on your birth record and select your birthplace from the city list. If you know the time, use the local clock time where you were born. The tool handles the time-zone adjustment.
If the time is unknown, use the option provided for that report. Some report types may ask for both birth hours. Follow those prompts, and keep the missing-time notes in mind when you read the result.
Where could you look for the time?
A birth record is a place to start. A parent or guardian may also have a note from the time. Records vary, and a remembered “early morning” is helpful context without necessarily being an exact hour.
You do not need to upload a birth certificate or other identity documents to use Joy Luck’s free chart. Enter only what the form asks for, and get permission before using another person’s details.
What can you take from a partial reading?
Start with a theme that interests you and compare it with your own experience. Does it help you understand something familiar, or give you a question you would like to explore?
If you find your birth time later, you can return with the extra detail. More information can make the chart more specific, but it still offers a traditional perspective for reflection, not certainty about the future.
A LITTLE MORE CLARITY
Your questions, simply answered.
Do I need the exact minute?
You can start with the hour you know. Exact minutes can matter near a chart boundary. If you only know “morning” or “evening,” use the unknown-time option where available.
What if only one of us knows our birth time?
Most relationship modes let you enter the known time and leave the other unknown. Follow the form’s prompts: some report types need both birth hours.
Should I convert my time to Beijing time?
No manual conversion is needed. Use the local clock time where you were born, and choose the correct birthplace from the list.
Will finding my time change the reading?
It can. Adding the hour may change the elements and animal patterns, and timing near a boundary can affect other details too. Create a new chart and read it with the added information in mind.
