Editing Sabbath in Christianity (section)

===Sabbath timing===
The Hebrew [[Shabbat]], the seventh day of the week, is "Saturday" but in the [[Hebrew calendar]] a new day begins at sunset (or, by custom, about 20 minutes earlier) and not at midnight. The Shabbat therefore coincides with what is now commonly identified as Friday sunset to Saturday night when three stars are first visible in the night sky. The Sabbath continued to be observed on the seventh day in the early Christian church.{{NoteTag|The civil calendar of the ancient Roman Empire, the [[Julian calendar]] (founded in 45 BC), marked days loosely in general practice, since the timing of midnight was difficult to determine widely at that time. Thus, the early church easily adopted for its own use the Hebrew calendar's sunset-to-sunset formula for marking the days, even after it began to calculate Easter according to the Julian calendar. Its daily cycle of church services began with Vespers, which was often celebrated just after sunset, in the early evening. This pattern made its way into both Roman and Eastern liturgical practice, and continues in use in the [[Eastern Orthodox Church]] to this day.}} To this day, the liturgical day continues to be observed in line with the Hebrew reckoning in the church calendars in [[Eastern Orthodox Church|Eastern Orthodoxy]] and [[Oriental Orthodoxy]].<ref>Canon of Holy Saturday (Orthodox), Kontakion: "Exceeding blessed is this Sabbath, on which Christ has slumbered, to rise on the third day."</ref> In the [[Latin Church]], "the liturgical day runs from midnight to midnight. However, the celebration of Sundays and of Solemnities begins already on the evening of the previous day".<ref>{{cite web| url = https://www.liturgyoffice.org.uk/Calendar/Info/GNLY.pdf| title = Universal Norms on the Liturgical Year and the Calendar, 3}}</ref>

In non-liturgical matters, the canon law of the Latin Church defines a day as beginning at midnight.<ref>{{cite web |url = https://www.vatican.va/archive/ENG1104/__PS.HTM |title = Code of Canon Law, canon 202 §1 |website = www.vatican.va }}</ref>
