How to Remove a Date From a WordPress URL

1. Open your Web browser and navigate to your WordPress dashboard at www.mywebsite.com/wp-admin, where mywebsite.com is the domain of your website. Enter your user name and password to continue.
2. Click 'Settings' in the bottom-left corner of the page, and then click 'Permalinks.'

3. Click a radio button under 'Common Settings' to select the permalink structure that you want to use. The common settings allow you to have WordPress use items such as the month, day, the name of the post or the post's number. Alternatively, click the 'Custom Structure' radio button and define a permalink structure of your own using tags such as '%postname%' and 'tegory%'. The full list of available permalink tags is available at WordPress.org.
4. Click the 'Save Changes' button to begin using the new permalink settings. WordPress adjusts the permalinks for all of your existing posts automatically.
