A license is valid for 90 days: don't apply early just to "have it in hand"
A marriage license isn't a document that stays valid forever once issued. It has a shelf life. And plenty of people apply early for peace of mind and end up letting it expire.
Two numbers to look up
Every county has these two, and they pull in opposite directions:
- Waiting period: how many days after issuance before you may hold the ceremony
- Validity: how many days after issuance the ceremony must be completed
The waiting period pushes you later, the validity pulls you earlier. Your ceremony date has to land between them.
California's numbers
From the California Department of Public Health (CDPH) official page:
"Marriage licenses are valid for 90 days from the date of issuance. If you do not get married within 90 days, the license will no longer be valid. You must purchase a new license."
Valid 90 days, and expired means buying a new one. California has no waiting period You can hold the ceremony the day it's issued. The same page also states explicitly that "Blood tests are NOT required to obtain a marriage license in California." (Blood tests are an impression many people carry from old films; California dropped them long ago.)

Other states differ widely
90 days is not a national standard. Some states allow only 30 or 60, and some impose a 1- to 3-day waiting period (you can't marry the same day the license is issued). This is set state by state and even county by county, with no general rule to apply.
Look it up on the official clerk site for the county where the ceremony will be. This is the same step as item 1 on the checklist, so just note both numbers down while you're there.
"Better to have it in hand" backfires
This is the most common miscalculation. The date isn't quite settled, so you get the license out of the way and stop worrying about it. Then the date slips by two weeks, or was four months out to begin with, and the license is long since void.
Expiry costs more than money (the fee is paid again). It costs time: both of you taking time off again, another trip, another appointment. And if you already wrote your post-marriage name on that license, the void one has to be redone from scratch.
The right order is: lock the wedding date first, then work backwards to the licensePick a day inside the window that satisfies both the validity and waiting period. Two to four weeks before the wedding is usually most comfortable. The document is fresh, and there's still time to redo it if something was filled in wrong.
Special note: destination weddings
If you're flying to another state to marry, the waiting period becomes critical: a state with a 3-day wait means you can't fly in Friday and marry Saturday. The itinerary has to shift earlier. Confirm this before booking flights, not after you arrive.
In one line
Set the date first and work backwards to the license; look up the waiting period and validity, because both are set by the county.
