Kerian Calendar

About the Kerian Calendar

The Kerian Calendar is a modern reimagining of time built around base-8 principles and a rhythmic 8-day week. Designed for clarity, flexibility, and personal resonance, it offers a new way to track days, plan events, and mark meaning in your life. Whether you're interested in alternative systems or simply want a calendar that adapts to your flow, the Kerian Calendar gives you more control over how time is shaped.

This is a manual style calendar meaning everything can be adjusted. For convenience (2025 or 3751): Jan 1st starts Ozon(D:4), and Dec 1st starts Aqua(A:1). There's a pattern that goes like this, every month ending with day 40, it'll be the same start of the day next month exept on October unless it's leap year. And if you look up at the moon during that same time, it'll be the same moon at the end of the next month. The same start of the month ends with a familar moon.

Key Features

• 8-Day Weeks: Each week features eight uniquely named days inspired by both planetary order and Earth’s atmospheric layers: Aquaday, Tropaday, Stratoday, Ozonday, Mesoday, Thermoday, Exoday, and Posiday.
• Base-8 Numbering: All dates use octal (base-8) numbers, offering a consistent and logical system that aligns with computing and rhythmic structures.
• Color-Coded Days: Assign a unique color to each day by starting your note with a hex code — perfect for visual organization and mood tracking (e.g., #ff0000 urgent task).
• Custom Week Alignment: Manually set where the week day appears in the grid, so your week can always start in the top-left corner or wherever fits your needs.
• Manual Day-One Selection: Choose which day of the week day-one should fall on — ideal for tradional calendar alignment.
• Save Notes to Any Day: Each calendar square supports text notes, which are saved automatically and persist across sessions.
• Export & Restore: Easily export all your notes and settings to transfer them to another device or browser. Tip, only use one device with one particular browser at a time. Notes and settings do not auto save between multiple browsers or devices.

Designed for Flexibility

Traditional calendars are built around legacy systems. The Kerian Calendar encourages a shift toward patterns that better reflect natural cycles and mental clarity. Simply, it's more educational. And because there are 8 days per week on the calendar, the last days are never split in half. It's always a full "square" day on the Kerian Calendar.

Sync at Your Own Tempo

Whether you're tracking lunar phases, assigning personal rituals, or syncing with your own productivity cycles, this calendar is built to grow with you. By decoupling from rigid 7-day structures, it becomes a more adaptable framework — perfect for daily journaling, spiritual tracking, or project planning.

Pronunciation guide

AH-kwuh-day, TRAW-puh-day, STRAT-uh-day, OH-zun-day, MEH-sow-day, THUR-moh-day, EKS-oh-day, PAA-zih-day. All have a rhythmic trisyllabic flow.

Suggestion for EXO and POS being the new octal weekend. If looking for every 7th day, it occurs diagnally to the left. So every next sabbath day will be a new week day. Think of it as a way to have a newly themed sabbath rest day. Option to take the Sabbath off and Posiday. Or Stick to EXO and POS.

There's a limit to how many characters can be saved into all the notes combined, so I suggest every other leap year to create a new file. About 4,000,000 letter characters can be saved in one local JSON file.
