A timeline maker for worldbuilding, with custom calendars
Date every event the way your world does: in its own months, eras and intercalary days. Put it on your own map, link the houses and factions that shaped it, and let a reader scroll the whole history at any scale. The timeline below follows the Thearchy of Slalt in its own Tideshell Reckoning, from the Age of the Drowned Kings to year 775.
A calendar that belongs to your world
Name the months, set how long each one is, add a leap rule and intercalary days, and define the eras your history is dated in. Every item, label and the axis then speak your calendar.
- The Tideshell Reckoning has months of different lengths, intercalary days outside them, and a leap rule of its own.
- Eras can count forward or backward, like an Age of the Drowned Kings that runs down to the Covenant.
- Readers can switch to relative time, and one calendar is shared across all your timelines.
Pro & TeamSetting up a custom calendar comes with Pro and Team. One you already have keeps working on every plan.
Your own map, with your own places
Upload the map of your world and place events, journeys and borders on it. Switch the timeline to its map and every pin leads back to its moment.
- A place can be a point, a route or a region drawn on the image.
- Add an uncertainty radius where a place is only roughly known.
- Set a default map, and readers, share links and embeds all see the same one.
Pro & TeamUploading a map comes with Pro and Team. Placing things on a map you already have works on every plan.
Houses, factions and the people in them
Keep the people, places, gods and groups of your world as entities of their own, linked from every item they appear in.
- Choose a kind for each entity, such as person, place or group, or add a kind of your own.
- A relation is a typed link between two entities, such as ally of or member of.
- Public entities get their own page, with every item that links them.
Dates that read the way a reader wants
Dates stay as you wrote them. A reader of a world with a custom calendar chooses between your calendar and relative time, counted from the start of your count.
- Write a date as precisely as you know it: a year, a month or a day.
- Add a ± where a date is only roughly known, and the edge of its bar softens on the axis.
- Eight real-world calendars are there too, among them Julian, Hijri and Hebrew, for a world that borrows from ours.
Coming from a wiki or a spreadsheet?
A wiki holds the lore, but not the order it happened in. Here every event sits on one axis, and a reader sees at once what came first.
A spreadsheet can count days in a calendar you invented, but you convert every date by hand and the reader gets rows of numbers. A custom calendar does the counting.
Another worldbuilding tool keeps your history in its own format. Here the items, entities and sources stay yours: download a copy of everything as one zip file whenever you like.
