The General Settings let you change many of the items that control how your blog is displayed, such as the title, tagline, timezone, and date/time formats. Click Settings from the left hand menu in your Dashboard to access these settings.
The first setting you will see is Site Title. The Site Title is displayed in the title bar of a web browser and is displayed in the header for most themes.
Tagline is next and is a short description or catchy phrase to describe what your blog is about. Some themes will display the tagline in the header or in the sidebar.
Now that WordPress has been installed, do not touch the values in these fields unless you are specifically instructed to do so in the documentation or instructions for a site move. Changing these values without carrying out the proper steps in the correct order will stop your site from working correctly and make it impossible for you to login to correct the problem.
The Email Address is where all comment moderation emails are sent. This can be different from the email address used for blog activity notifications by plugins. It is in your best interests to keep this email using your domain (i.e. firstname.lastname@example.org instead of email@example.com) in order to prevent your webhost from treating your email as spam.
Note: This also will not be the email address used by WordPress when users register. WordPress sends all its emails from ‘firstname.lastname@example.org’ as this is more compatible with hosts.
Your blog’s timezone is set to Coordinated Universal Time, UTC by default, which is in London, UK. If you live in a different area of the world you will likely want to change this option. The current UTC time is listed to the right to make it easier to determine your timezone offset. As an example, when Daylight Saving Time is not going on, Boston, MA would be UTC-5.

The Date Format lets you select how dates will be displayed on your blog. Several popular choices are available, as well as a custom option.
The Time Format setting is just like the date format, but sets how times will be displayed on the blog. For example, you may choose to use a 24 hour or 12 hour clock via your Time Format.
Time formatting uses PHP standard format, which can be confusing. You can review Formatting Date and Time, which explains the code.
The Week Starts On setting, is only used if you are using the calendar widget. This setting allows you to select what day is displayed in the first column of the calendar.
