Generate weekday names for a fantasy or sci-fi calendar: Old English-style compounds like Hearthday and Tithesday, god-days like Vaelsday, elvish and latinate day names, short Eberron-style syllables, Norse and Germanic -dag and -tag forms, and ceremonial days like the Day of the Long Shadow. Built for worldbuilders, novelists and game designers.

About weekday names

Real weekday names were built from just two ideas, and a fictional week feels authentic when it borrows one of them. The Germanic week names days for gods and heavenly bodies: Sunday and Monday for the sun and moon, Tuesday, Wednesday, Thursday and Friday for Tiw, Woden, Thor and Frigg, and Saturday for Saturn. Portuguese, Hebrew, Arabic and Chinese simply count them and reserve a name only for the holy day or market day. The French Revolutionary calendar went further and invented a ten-day week of Primidi through Decadi.

For worldbuilding, the god-day approach tells readers what the culture worships in a single word: a week of Vaelsday, Ormsday and Kethsday implies a pantheon before you describe it. Activity days (Marketday, Washday, Tithesday, Restday) tell readers how people live. Eberron-style single syllables such as Sul, Mol and Zol, or elvish names like Elenril and Silmaren, give a week that sounds foreign without needing translation. Decide how many days your week has, then pick one register and keep to it; a seven-day week that mixes Hearthday with Lunestre reads as an error unless two cultures are meant to be sharing a calendar.

Most fictional weeks end with a day that is different in kind, a rest day, holy day or market, so give the last day a name that stands apart.

How to choose weekday names

  • Choose the week length first. Seven days feels familiar, ten (a tenday) is common in D&D settings, and five, six or eight days signal a genuinely different culture.
  • Keep one register across the whole week: all Old English compounds, all god-names, all elvish, or all numbered. Mixing inside one calendar only works if two cultures are sharing it.
  • Name at least one day for something sacred or practical (Restday, Tithesday, Marketday, Kingsday); it gives your characters a reason to say the day's name aloud in dialogue.
  • Keep day names to one or two syllables plus the suffix so sentences like 'the third Hearthday of Frostfall' stay readable.
  • If you use -day in English, pair it with a matching month-name style from the fantasy month generator so the two halves of the calendar sound like they were invented by the same people.

Frequently asked questions

How many days should a fantasy week have?

Seven is easiest for readers, but ten-day weeks (tendays or decades) are well established in fantasy and five- or eight-day weeks are good for non-human cultures. Whatever you pick, make it divide your month or year neatly so festivals always fall on the same weekday.

Why do so many fantasy weekday names end in -day?

Because the English suffix comes from the real Germanic names (Sunnandæg, Thunresdæg) and readers instantly parse Hearthday or Wolfday as a weekday. Other languages used -dag, -tag, dies and -bi, and this generator includes those forms too for calendars that should not sound English.

Can I use real weekday names like Monday alongside invented ones?

You can, but it usually breaks immersion. Instead translate the idea: Moonday for Monday, Sunsday for Sunday, then invent the rest in the same style so the familiar days anchor the reader without pulling them out of the world.

Are these weekday names free to use in my novel or campaign?

Yes. The names here are original or drawn from public-domain sources such as Old English, Latin and the French Republican calendar. Avoid lifting a complete week verbatim from a published setting like Eberron or Golarion if you plan to sell your work.
