Inside ForgeTales
Calendars for your worldbuilding
Not every world counts twelve months around one moon. ForgeTales lets you build your world's own reckoning of time — custom months and weekdays, multiple moons with their phases, holidays and eras — and then actually use those dates across your timeline and your writing.
Keeping your story's timeline consistent
One of the hardest parts of building a story is keeping its temporal structure coherent: journeys that arrive too soon, characters aging at different speeds, festivals that fall twice in the same winter, moons that are full whenever the plot needs them. Small details, but readers notice them.
A calendar shared by the whole project is the simplest fix. In ForgeTales the calendar is not a side decoration: your timeline, your events and your seasons all speak the same dates, so your world's history and its way of measuring time always agree.
Gregorian, Harptos or entirely your own
Start from a preset when the reckoning already exists: the Gregorian calendar for contemporary fiction, or the Calendar of Harptos with its months and holidays for campaigns set in the Forgotten Realms. Pick one and your calendar is ready to use right away.
Or invent time from scratch. Name your months, decide how many days make a week and how many weeks make a month, and define your own eras: you can count the years from a great war, the founding of an empire or the cataclysm that shaped your history.

Your plot events, laid out on real dates
The calendar does not live apart from your story. Every event you create in your plots can land here: the inbox collects the ones without a date yet, and you drag each one onto the day it happens. Multi-day events stretch across the month, colored by the plot they belong to.
That is when chronology stops being guesswork. You see at a glance which events overlap, which storylines coincide on the same dates and where a character's movements stop adding up. Better to find out now than in the reviews.
Give the year a climate
Worlds have weather patterns, not random rain. Pick a climate preset for the region your story lives in: tropical rainforest, arid desert, Mediterranean, oceanic, humid continental, subarctic, tundra or alpine. ForgeTales draws the year's temperature and rainfall curves month by month.
You can also source the climate from a location in your wiki, so the calendar reflects the place your chapter actually happens in. The chart tells you the temperature and rainfall for every month of the year, so you never have to improvise them mid-scene.

Weather and moons, day by day
From that climate, every single day gets its own weather: temperature, chance of rain, cloud cover, wind. Hover over a date and you know what the sky looked like that night. Moon phases run alongside, day after day, which matters when your tides, rituals or werewolves depend on them.
This is texture you can write with. When you describe a scene, you can check that day's weather and moon instead of improvising them, and your scenes gain the kind of consistency readers feel without knowing why.

What you can do with it
Time, invented from scratch
Decide how many days make a week and how many months make a year. 'Aeon, Year 342' becomes a real, computable date in your world.
Moons, weather and holidays
Track lunar phases — a Twin Eclipse, if you like — alongside festivals and seasons. The texture of time is worldbuilding too.
Connected to your history
Your timeline events use these dates natively, so your world's history and its way of measuring time always agree.
Frequently asked questions
Can I create multiple moons and lunar phases?
Yes. Your calendar can track custom moons and their phases — useful when your tides, rituals or werewolves depend on them.
Do my custom dates work in the timeline?
Yes, that is the point: events on your timeline can be dated in your own eras, months and years, keeping your chronology consistent.
Why does a worldbuilding app need a calendar tool?
Because time is one of the most common places fictional worlds break. A calendar your whole project shares means festivals, ages and journeys stop contradicting each other.
