** Estonian and Portuguese languages have numbered days (''esmaspäev, segunda-feira'' etc) for the week days, substituting the traditional names. Saturday, though are ''lauapäev'' and ''sábado'' (sabbath) and Sunday ''pühapäev'' and ''domingo'' (Lord's day)).

** In the ''[[VideoGame/HarvestMoonAWonderfulLife Wonderful Life]]'' games as well as the remake ''VideoGame/StoryOfSeasonsAWonderfulLife'' there are still four seasons, but only ''ten'' days per season, with no designation for days of the week).

* ''Literature/ASongOfIceAndFire'' is set in the second to third century after Aegon's Landing. The seasons are random in length, but are much longer than the years, making it uncertain what a "year" actually means (probably related to a complete rotation of the sun, our own calendar is measured as such, rather than the passing of seasons). WordOfGod clarifies that, unlike on Earth, there's 12 moon turns in a year.

* ''VideoGame/HarvestMoon'':

** Most of the games use years made up of four thirty-day seasons. The years themselves count up from the start of the game, which is usually when the player character arrives in town. The ''VideoGame/RuneFactory'' spinoff series takes this one step further by combining Saturday and Sunday into "Holiday", meaning that every day of the year will always be on the same day of the week.

* In Creator/VernorVinge's ''Literature/ADeepnessInTheSky'', interstellar traders have done away with not just years and months, but also with days, hours and minutes. All timespans are measured in (appropriate powers-of-thousands of) seconds, with dates simply being the number of seconds since the UsefulNotes/{{UNIX}} epoch (with some unspecified [[ShownTheirWork but explicitly mentioned]] relativistic frame corrections) — though in-universe [[FutureImperfect it is most commonly thought that the zero-second was at the first moon landing]]. Settled planets all have their own calendars. One way the traders know they have stayed too long is when they start using the locals' calendar.

** Most software uses "UsefulNotes/{{UNIX}} time", counting up the number of seconds (or milliseconds) since 1 January 1970, known as the "UNIX epoch". It's kept in sync with UTC, which uses occasional leap seconds to keep it consistent within a second of Greenwich mean time, so its value is not ''exactly'' equal to the number of seconds elapsed since then. Interestingly, this led to a [[MillenniumBug Y2K-like]] phenomenon known as the "[[http://en.wikipedia.org/wiki/Year_2038_problem 2038 problem]]", referring to the year when a signed 32-bit integer will overflow when reading UNIX time (but most systems nowadays are 64-bit, which would last you about another 300 billion years).

* '' An episode of Pokémon the Series: XY hints that the Pokémon world is either a few decades out of sync with our world, or they use a different calendar. Regardless of which is true, the year in the anime is implied to be 1958 or possibly later.
