Finding Your Birth Time
California records the time of birth on the long-form certificate, not the short one. Here is which version to order, who holds it, what it costs, and what to do when the time is missing.
This is where most people get stuck. They already have a birth certificate, they look at it, there is no time on it, and they conclude the time was never recorded. Usually it was.
California issues two things. The certified copy, often called the long form, is a reproduction of the original record and includes the hour of birth, the hospital, and the parents' details. The abstract, or short form, is a summary and leaves the time off. If the document in your drawer is a single short page, it is probably the abstract.
| Source | Covers | Typical wait |
|---|---|---|
| County recorder, county of birth | Births registered in that county | Often same week, sometimes same day in person |
| California Department of Public Health, Vital Records | Statewide, 1905 to present | Several weeks by mail |
| Hospital medical records department | Delivery notes where the certificate is incomplete | Varies, and usually requires a written request |
California restricts certified copies to the person named on the record, a parent, a legal guardian, a spouse or domestic partner, a child, grandparent, grandchild or sibling, and a few legal roles. You sign a sworn statement to that effect. Ordering your own record is straightforward. Ordering a cousin's is not.
Two things happen often enough to plan for.
The first is that the hour box was left blank. Hospital medical records are the next place to look, because the delivery notes are a separate document from the certificate and frequently survive when the certificate is thin.
The second is that the time reads exactly on the hour or exactly on the half hour. Sometimes that is true. Often it is a nurse rounding while writing up a busy shift. A time of 7:00 PM should be treated as somewhere in a window rather than as a precise figure, and that window is wide enough to move a rising sign.
Baby books are underrated. More than once a client has given up on the paperwork, called their mother, and found the hour written in a baby book in her handwriting, usually more precisely than the certificate recorded it.
California observes daylight saving and always has in the modern era, so a summer birth needs the hour adjusted back to standard time before the chart is drawn. Any decent calculator does this for you, but it is worth knowing why the number you type is not always the number the chart uses. The full American daylight saving history is here.
The long-form certified copy does. The short-form abstract that many people already have at home usually does not.
The California Department of Public Health holds records from 1905 onward. The county recorder in the county of birth also holds a copy and is often faster.

Finding Your Birth TimeIf you were born in the US between 1945 and 1991, there is a real chance your birth time was recorded under a daylight saving rule your chart calculator does not know about. Here is how to check.
