"Remember the Sabbath day, to set it apart. Six days you labor and do all your work, but the seventh day is a Sabbath to Yahuah your Elohim." - Exodus 20:8-10
The Sabbath is observed from evening to evening (Leviticus 23:32). In biblical reckoning, each day begins at sunset, not midnight. This calendar calculates precise sunset times for your location to help you properly observe Yahuah's appointed Sabbath time.
