About this book

Who determines sacred time - Yahuah's Word and created witnesses, or inherited calendars, religious courts, sectarian systems, and modern assumptions?

The True Hebraic Biblical Calendar, Fourth Edition - Strengthened, Illustrated, Expanded, Revised, and Updated is a substantial 8.5 x 11 workbook study guide and field manual for restoring Yahuah's appointed times through Torah, creation, covenant, and evidence. It does not merely publish dates. It teaches the reader how the biblical day, week, Sabbath, month, year, and appointed times fit together as one covenant-time system.

Torah remains the governing foundation. The Prophets guard and call back. The Writings preserve the lived testimony of covenant time. The Apostolic Witness applies the established pattern in Messiah. Astronomical calculations, agricultural observations, historical sources, ancient manuscripts, rabbinic traditions, and modern calendar systems are examined as subordinate evidence rather than allowed to become a fifth authority.

This Fourth Edition carefully distinguishes direct command, created sign, historical record, inference, covenant conclusion, and Watchman's warning. That evidence discipline matters because calendar arguments often fail by making an observation sound like a command or by turning an inherited procedure into Torah. The reader is taught to ask not only, 'Is this claim possible?' but, 'What kind of evidence establishes it, and what authority is that evidence permitted to carry?'

The study works from the smallest units outward: the evening-to-evening biblical day; the continuous seven-day week and seventh-day Sabbath; the renewed lunar month; conjunction and the waxing crescent; twenty-nine- and thirty-day months; Aviv, barley, firstfruits, seasonal evidence, and intercalation; and then the complete annual cycle of Passover, Unleavened Bread, Firstfruits, Shavuot, Yom Teruah, Yom Kippur, Sukkot, and the Eighth Day.

Major competing claims are tested directly. The book examines lunar-Sabbath systems, first-visible-crescent authority, rabbinic calendar administration, Christian calendar assumptions, Enoch and Jubilees, Zadokite and Qumran calendar claims, Jasher, equinox-based rules, and other secondary systems. Each is required to show where its controlling rule is actually established and whether it adds to, subtracts from, or overrules Torah.

The governing model argued in this edition uses astronomical conjunction as the objective renewal of the lunar cycle, begins Month Day 1 at the next declared evening boundary after renewal, and treats the waxing crescent as visible confirmation. That administration is defended as a covenant conclusion rather than falsely presented as a word-for-word Torah command. The year is guarded through Aviv and representative agricultural evidence so that Passover and Firstfruits remain in their commanded season.

This is also a working study guide. Chapters include Four-Witness Scripture reading lists, governing claims, evidence boundaries, Watchman's verdicts, covenant-practice applications, glossaries, reflection and review questions with answers, fill-in-the-blank exercises with answer keys, charts, diagrams, decision matrices, and practical calendar-building tools. The goal is not merely to win a calendar argument. It is to form households, students, teachers, and assemblies capable of testing calendar doctrine and walking faithfully in Yahuah's appointed times.

Study. Learn. Apply. Grow. Share. Repeat.

Guard the month. Guard the Sabbath. Guard the appointed times.
