Marriage dates are part of the public record. In most areas they are published in the local newspaper and on the internet the following month. If you are looking for a marriage date that is not recent, there is no national index of marriage certificates or licenses, so you need to request this information at the state or local level. You can find out the date someone got married by searching the internet and asking city officials.
Steps
Method 1 of 3: Recent Marriages

Step 1. If possible, find out the location of the wedding
This will allow you to identify any newspapers that may have published the date.

Step 2. Find the full names of the bride and groom
Discovering a middle name can allow you to achieve your results.

Step 3. Go to the website of the newspaper where the person was married
Search the names in the announcements or public records section.

Step 4. Visit a public library to search back issues of your local newspaper
You can also look up the records at the newspaper's headquarters.

Step 5. Use a search engine
Enter the person's name or include both names if possible.

Step 6. Browse through multiple pages of records
Sometimes the wedding date may be listed on wedding blogs, Facebook accounts, or bridal magazine websites.

Step 7. Go to the place where the person was registered to receive wedding gifts
Call or look for ads online in the person's name.
Most records keep the name and date of the wedding, as well as potential gifts, for up to two years after the ceremony
Method 2 of 3: Marriage Records

Step 1. Check your state's marriage certificate index or repository
Not all states have these rates, but if they do, they can allow you to find the person's wedding day without going to an office.
Visit websearchguides.com/marriage_and_divorce_records.htm#partII to see if your state has a marriage certificate index

Step 2. Go to the municipal records office in the area where the person was married
Marriage licenses, which show the date of the ceremony, are given by city officials and a search can be performed at the registrar's office.

Step 3. Complete an on-site form to conduct a marriage record search
You may need to pay between 12 and 130 reais to do this.
You can do this search online through your municipality's website. You may need to present an account and credit card number to complete the online survey
Method 3 of 3: Online Agencies

Step 1. Search for personal information through a website or an agency
Remember that there is no national database of marriage records. So don't trust that by paying for a background check service they will provide this information

Step 2. Create an online account
Few agencies allow you to search without an account.

Step 3. Register for a free trial to access the records or pay to use the service
Remember that results are not guaranteed, even if you pay.

Step 4. Search through the online database
You can also pay for a full background investigation in which you learn other personal information beyond your wedding date.

Step 5. If possible, research the records the database has before paying
Some sites will display the years that are available to be searched in the state.
