The Calculated Hebrew Calendar has been a consistent instrument used by the church of God and the Jews, fostering unity in the tracking and use of time. This calendar, essential for worship and service to God, is not fully detailed with precise rules in the Scriptures, indicating that its authority and structure were established in the past under divine oversight. God, as the Sovereign Creator, would not leave something so vital to chance or human whim, ensuring that His children have a reliable means to respond to Him in worship. Historically, there is no record of any era of the church of God rejecting the Calculated Hebrew Calendar in favor of a self-designed alternative. Proposals for new calendars often introduce inconsistencies, such as reliance on visual sightings of the new moon, which are impractical for a worldwide operation and lead to confusion and division. The Bible does not specify detailed rules for determining seasons, new moons, or intercalation, nor does it mandate specific geographical points like Jerusalem for calendar calculations. Such specifics, including postponements or adjustments, are necessary for maintaining a consistent and predictable calendar but are not explicitly provided in Scripture. Postponements in the Hebrew Calendar, often placed around the beginning of Tishri, are calendrical reconciliations made for astronomical and practical reasons, ensuring preparation days before holy days or Sabbaths. These adjustments reflect a merciful intent to facilitate worship without undue burden, aligning with God's desire for feast days to be times of joy rather than privation. Critics of these postponements often overlook their necessity and the lack of biblical specificity, while themselves introducing unscripted elements into their alternative calendars. The defining issue surrounding the calendar is faith in God's faithfulness to provide and preserve an essential tool for His church. To challenge or change the Calculated Hebrew Calendar is to question His providence and oversight, implying a failure on His part to equip His children adequately for worship across centuries. God, in His unchanging nature, has ensured that the calendar serves as a unifying force, and any deviation from it risks spiritual ineffectiveness and disunity within the church.

The controversy over which calendar should be used to set God's holy days remains a persistent issue within the church, sparking strong opinions and disagreements. Many publications advocate for a return to what they call God's calendar or the biblical calendar, asserting that the Hebrew calendar is not biblical. Key points of contention include determining the beginning of the year, identifying when a new moon is new, the use of postponements, intercalation, and the debate between observation and calculation. Some also object to the names of the months on the Hebrew calendar, claiming they indicate it is not of God. A calendar, as defined by standard dictionaries, is a system for fixing the beginning, length, and divisions of the civil year, arranging days, weeks, and months in a definite order. However, no such tabular register or clear table for setting holy days exists in the Scriptures. The closest approximation is the list of holy days in Leviticus 23, which serves as a schedule of events arranged chronologically, yet lacks an underlying system for precise placement. Critics of the Hebrew calendar often attack its postponements and calculated method, arguing that the Bible does not mention postponements and that the calendar should be set by observation. Observation involves setting the new year and months based on visual cues like the green ears of barley and sightings of the new moon, while the calculated method of the Hebrew calendar uses astronomical and mathematical computations based on average speeds of heavenly bodies. Although observation is inferred in the Bible and historically documented in ancient Israel, it is subject to variables like weather, which can disrupt planning for holy days. The fixed Hebrew calendar, using average speeds, incorporates postponements as adjustments to harmonize with the irregular movements of heavenly bodies, enabling consistent planning and preparation for God's holy days across diverse regions. The postponements are not about human comfort but are necessary adjustments to keep festivals, the moon, the sun, and seasons in harmony over extended periods. They also reflect a respect for Sabbath observance by ensuring preparation days fall appropriately, preventing holy days from interfering with each other. The Hebrew calendar, despite not being perfect, works remarkably well, maintaining unity in observance and proving its value through consistent use over centuries among God's people.

Darryl Henson is using the calendar as a focal point to draw attention to himself and gain a following, claiming a conscience issue with it. He asserts that he and I will be reunited in the future to do the work of Joshua and Zerubbabel together, implying that I will repent and adopt his calendar. However, his calendar is just as wrong as the other eight or nine models circulating within the church of God. The issue of the calendar is far more serious than many realize. People are making critical decisions that may affect their salvation based on minimal research, often becoming victims of cleverly arranged treatises. There is a glut of information available, much of which is unreliable, and individuals must be cautious and patient in discerning the truth. Those advocating for calendar change often argue that the calculated Hebrew calendar is too complex and must be simple for common people to grasp. They also claim that the Jews deliberately manipulated the calendar with postponements to make festival timing more convenient, avoiding conflicts with preparation days or the weekly Sabbath. However, nowhere in the Bible does God indicate that the calendar must be simple. The creations of God, including His Word, are complex, and the calendar fits into this pattern of complexity, requiring understanding through yielding to Him. The calculated Hebrew calendar is the calendar of the nation of Israel, in existence since Israel's beginnings. God's purpose is worked out through Israel, and the church is seen as a part of Israel, an institution within it. The faithful God supplies all the needs of His people, including a calendar to keep the holy days and the weekly Sabbath, as evidenced from the time of Exodus when Israel already had a calendar distinct from Egypt's solar calendar. Historical evidence shows that the church, from the time of Herbert Armstrong, has consistently used the Hebrew calendar, even through various challenges and researches. No record exists of the church using any other calendar throughout its history. Despite minor adjustments, such as the correction of Pentecost counting, the underlying calendar system remained unchanged. Major spin-off groups from the Worldwide Church of God have independently decided to remain with the calculated Hebrew calendar, demonstrating a pattern of God's guidance in this matter. The calendar changers suggest that during the Tribulation, access to a calendar may be impossible, questioning how festivals can be kept. Yet, the Bible indicates that conditions during the Tribulation will be so severe that even keeping the weekly Sabbath may not be possible, underscoring that the issue is not simplicity but adherence to the correct calendar provided by God. The notion that the Jews have deceived God regarding the calendar for over 1600 years, only to be corrected now by these changers, is presumptuous. If multiple differing calendars exist within the church of God, it raises the question of whether God is divided or unfaithful in not providing one unified calendar. The issue is God's faithfulness, as these changers accuse Him of neglecting His church until their arrival. Evidence from the Talmud about some Jews not using postponements at the time of Christ is acknowledged, but the Talmud is a commentary, not the Bible, and contains conflicting opinions. Authority over the calendar resided with the Jerusalem rabbis, not the Babylonian rabbis who made such statements. Hillel II, of the Jerusalem school, published the rules used by the Jews and the church of God. In ancient Israel, the beginning of a new month was declared by the bet din in Jerusalem through signal fires to maintain unity and prevent individuals from deciding for themselves, a principle now undermined by multiple calendars in the church due to people doing what is right in their own eyes. The spirit of changing festival dates aligns with the spirit of the Beast, who seeks to change times, as noted in Protestant commentaries
