About this app
Day 4 is a biblical calendar — a witness of time for the appointed times, prayer, Scripture, and the rhythm of the heavens.
On the fourth day of creation, the sun, moon, and stars were given “for signs, and for seasons” (Genesis 1:14). Day 4 follows the 364-day biblical calendar shaped by that witness — an equinox-anchored year with a fixed Sabbath (Shabbat) rhythm — helping you walk in step with the appointed times.
TODAY, AT A GLANCE
• Today’s date in the 364-day biblical calendar, alongside the civil date
• The Year Dial — the whole 364-day year in one ring, with today marked
• The next weekly Sabbath, with a clear countdown
• The moon — tonight’s phase and illumination
• A devotional verse for every day, and a gentle streak with grace — one missed day never breaks it
THE CALENDAR
• Month and year views of the biblical calendar, with feasts, seasons, and pause days
• Scriptural and historical events on the calendar — open any to read its story, scriptures, sources, and study notes
• A year navigator to visit any sacred year
• The Ages — walk the eras of history from Creation onward, laid along the sacred year
• Signs in the heavens — solar and lunar eclipses, blood moons, and equinoxes, set on the days they fall
• A Sacred Year Planner to prepare for each feast, with export to your calendar app
• The Scroll of Generations — trace the generations from Adam (Premium)
THE APPOINTED TIMES
• The yearly feasts and holy days (moedim), with countdowns and clear explanations
• Feast guides that explain each appointed time and its scriptural roots
• My Days — keep your own remembered days and anniversaries on the sacred calendar
WHY 364 DAYS
• A 364-day calendar year of 52 whole weeks, so every feast day and Sabbath keeps its place
• The same family of calendars witnessed in the books of Enoch and Jubilees and in the Zadok priestly courses found at Qumran — often called the Enoch calendar or creation calendar
• Fixed Sabbaths all year, with a clear countdown to the next Sabbath
MANNA — DAILY SCRIPTURE CARDS
• Pick the card of the day: scripture and encouragement drawn from themed decks — the Word, the Season, the Feast, the Sign, and more
• Save a thought about the day, and share any card as a beautiful image
THE HOURS OF PRAYER
• The biblical hours of prayer, reckoned from the sun where you are — morning, midday, evening, and the night watches
• Guided prayers for each hour, prayer history, and themed journeys
• Prayer-hour notifications at each appointed time
READ AND STUDY
• Read the Bible in the app, across translations — the Old and New Testaments, offline
• Highlight in five colors, take verse notes, and save verses to your library
• Search the Bible, even offline, and adjust the text size
• A Journal that gathers your notes day by day, with search and export
• Why Day 4? — the full reasoning behind the calendar, right inside the app
ALWAYS IN VIEW
• Home Screen widgets: Today, the Year Dial, Next Sabbath, and Biblical Time
• Reminders you choose: prayer hours, night watches, sunrise, sunset, My Days, and feasts
YOURS, EVERYWHERE
• Start as a guest — no account needed. Sign in with Google, Facebook, or email
• Your notes, highlights, saved verses, and prayer history sync across your devices
• Set your sacred birthday and see your own day on the calendar
