Keep Sabbath is a plugin to help those that want to keep the 7th-day Sabbath and Biblical Holy days set-apart (holy) by not buying or selling on them. (Genesis 2:2,3 ; Isaiah 58:13,14 ; Amos 8:5 ; Nehemiah 10: 31 ; Jeremiah 17:21,22 ; Matthew 6:33 ; Acts 16:13)
You can input specific page URLs to redirect to a certain page URL during the Sabbath and/or specified Holy days. This is useful for e-commerce sites or any site that has online purchasing. It will automatically start redirecting when the Sabbath or Holy days begin, and stop re-directing afterwards.
The timing is based on the understanding that Biblical days begin at sunset and end at sunset the following day.
<ul>
<li>For the 7th-day Sabbath, this means from sundown Fri. to sundown Sat. it will automatically redirect with no extra configuration from you. </li>
<li>For Biblical holy days (Passover, Pentacost, etc) this means that the day will start sundown the day prior to the day you specify in the admin Holy Day Dates setting.</li>
</ul>
<h3>Setting up</h3>
<ol>
<li>
Navigate to the Keep Sabbath settings by either clicking the Settings link on the plugins page, or through the Settings > Keep Sabbath menu in the sidebar.

<li>

</li>
<li>
Click the Save Changes button, and you’re done! The plugin will automatically redirect the URLs to the given page on Sabbath or a Holy day.
