For grounded, sci-fi, or alternate-history worlds
Use a real Gregorian calendar. Precise day, month, and year sorting for worlds that run on Earth's timeline — historical fiction, near-future sci-fi, alternate history.
Worldbuilding Timeline Maker
Organize your world's eras, histories, factions, and lore into one visual chronology you can actually navigate.

Give your world a coherent history
Deep worldbuilding produces a lot of history — creation myths, empires, plagues, treaties, and the slow rise and fall of factions. Without a timeline, that lore lives in disconnected documents and contradicts itself over time. A worldbuilding timeline pulls everything into one chronological view so you can see the shape of the world, not just the pile of facts.
Add events for everything that matters: the founding of a kingdom, a war's beginning and end, a ruler's reign, a technological breakthrough. Use date ranges for anything that spans years. Use colored era bands to mark the great ages of your world.
Build a cast of reusable entities — define once, link everywhere
Worlds are made of relationships. Create a reusable entity for a character, location, or faction once, then attach it to every event it touches. No copying and pasting names across twelve documents. When you filter by that entity, the timeline shows only the events it appears in — its entire arc in one unbroken thread.
- Reusable characters, locations, and factions
- Filter the whole world's history to a single entity
- Per-faction view to trace its rise, fall, and alliances
- Continuity checks for impossible or missing dates
Trace cause and effect across an age
The best worldbuilding is causal. A drought causes a migration. A migration foreshadows a border war. A dynasty's fall is the consequence of a single assassination. Link events by relationship and the history of your world stops being trivia and becomes a chain readers — and you — can follow.
Continuity checks flag the moment your dates contradict a dependency, so a thousand years of cause and effect stays internally consistent.
Real or invented calendars — your world, your rules
For high fantasy and invented worlds
Define your own calendar with custom era names and year numbering. "The Long Winter, Year 44" sorts and spaces correctly — no gymnastics to make invented dates work.

Worldbuilding timelines to model yours on
However your world is organized, one of these starting shapes will get you there faster than a blank page.
Empire rise & fall
Founding, golden age, overreach, and collapse — the life cycle of a civilization charted as overlapping date ranges.
Pantheon & mythology
Gods, divine wars, and the mythic events that shaped the world before recorded history began.
Technology & magic eras
How power changed hands as a world moved from one age of magic or technology to the next.
Faction power map
Each faction in its own band so you can see who held power, who allied, and who fell — century by century.
