Day 4 — A Witness of Time
Biblical calendar & prayer
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
On the fourth day, God made the lights that keep time. Day 4 puts that calendar beside yours — Sabbaths, feasts, signs in the sky. An invitation, not an obligation.
Day 4 is a witness of time — a sacred calendar for 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 a 364-day sacred calendar shaped by that witness, helping you walk in step with appointed times day by day.
TODAY, AT A GLANCE
• Today’s date in the sacred 364-day calendar, alongside the civil date
• The Year Dial — the whole sacred 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 sacred calendar, with feasts, seasons, moon phases, 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 and see what happened in it
• 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, and export to Apple Calendar
• The Scroll of Generations — trace the generations from Adam (Premium)

• 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
