The Yoruba system of marking time preserves layers of pre-modern, colonial, and contemporary influence in a single living vocabulary. Traditional Yoruba society used a four-day week organized around major orishas, with each day dedicated to a particular deity and to the market in a particular town. The arrival of Islam, then Christianity, then British colonial administration introduced the seven-day week, which in turn was rendered into Yoruba using both traditional sacred associations and direct phonetic borrowings. The result is a calendar vocabulary that simultaneously names Sunday after the orisha-tradition idea of "the day that does not die" and offers calque-style English borrowings for clock time.
This reference catalogues both the traditional and modern systems: the four-day Yoruba market week, the seven-day Christian and Islamic week as rendered in Yoruba, the months of the Gregorian calendar, time-of-day vocabulary, the system of relative time expressions such as òní, àná, and ọ̀la, and the structures used to tell clock time. For grammatical context on numbers (essential to telling time), see the Yoruba numbers and vigesimal system reference.
The Days of the Week
Modern Yoruba speakers use a seven-day week parallel to the international calendar, but the names retain traditional resonances. Each day name begins with Ọjọ́ ("day"), often shortened in casual speech.
| English | Yoruba | Etymology / Note |
|---|---|---|
| Sunday | Àìkú / Ọjọ́ Àìkú | "Day of no death" / "the immortal day" |
| Monday | Ọjọ́ Ajé | "Day of wealth / Aje (orisha of wealth)" |
| Tuesday | Ọjọ́ Ìṣẹ́gun | "Day of victory" |
| Wednesday | Ọjọ́rú | "Day of confusion" (sometimes called Ọjọ́ Iṣẹ́, "day of work") |
| Thursday | Ọjọ́bọ̀ | "Day of return" |
| Friday | Ẹtì / Ọjọ́ Ẹtì | "Day of failure" or "ill-fortune" (now neutral) |
| Saturday | Àbámẹ́ta / Ọjọ́ Àbámẹ́ta | "Three regrets" or "day of regret" (origin debated) |
The traditional sacredness of these days is preserved in their names. Àìkú ("no death") makes Sunday the day of long life, fitting for both Christian Sabbath observance and traditional rest. Ọjọ́ Ajé invokes Aje, the orisha of wealth and commerce, making Monday a fitting market opener. Ọjọ́ Ìṣẹ́gun ("day of victory") is sometimes interpreted as the day of the orisha Ogun (war/iron), though linguistically distinct from the orisha's name.
"Ọjọ́ ti ò bá pẹ́ jíjí, ó ń yára mọ́jú" — A day that does not delay waking hurries to dawn. Yoruba time philosophy: each day asserts itself.
The Traditional Four-Day Week
Before adoption of the seven-day week, traditional Yoruba society organized its market and ritual life around a four-day cycle, called ọṣẹ̀ (week, but originally meaning the four-day cycle).
| Day | Yoruba | Dedicated To |
|---|---|---|
| Day 1 | Ọjọ́ Ọbàtálá | Obatala (orisha of creation, white cloth) |
| Day 2 | Ọjọ́ Ògún | Ogun (orisha of iron, war, technology) |
| Day 3 | Ọjọ́ Jákútá | Sango (also called Jakuta in older usage) |
| Day 4 | Ọjọ́ Ọ̀ṣun | Osun / Orunmila (rivers, divination) |
This system is preserved in ritual contexts, particularly in Ifa divination practice and in Candomblé and Lucumí (see the Yoruba diaspora varieties reference). Many Yoruba towns still hold their major markets on a four-day rotation, and the phrase ọjà ọjọ́ mẹ́rin ("four-day market") refers to this rhythm.
Months of the Year
Modern Yoruba months are largely calques or transliterations of English. Older texts sometimes used purely Yoruba descriptive names for months, but these are no longer in everyday use.
| English | Yoruba (Modern) | Yoruba (Traditional) |
|---|---|---|
| January | Oṣù Ṣẹ́rẹ́ / Janúárì | Oṣù Ṣẹ́rẹ́ ("month of rain-beginnings") |
| February | Oṣù Èrèlè / Fẹ́bùárì | Oṣù Èrèlè |
| March | Oṣù Ẹrẹ̀nà / Máàṣì | Oṣù Ẹrẹ̀nà |
| April | Oṣù Ìgbé / Ápíríìlì | Oṣù Ìgbé |
| May | Oṣù Èbìbì / Mè | Oṣù Èbìbì |
| June | Oṣù Òkúdu / Júnù | Oṣù Òkúdu |
| July | Oṣù Agẹmọ / Júlài | Oṣù Agẹmọ |
| August | Oṣù Ògún / Ọ́ọ̀gọ́sì | Oṣù Ògún |
| September | Oṣù Owewe / Sẹ́tẹ́ńbà | Oṣù Owewe |
| October | Oṣù Ọ̀wàrà / Ọ́kọ́tóbà | Oṣù Ọ̀wàrà |
| November | Oṣù Bélú / Nòfẹ́ńbà | Oṣù Bélú |
| December | Oṣù Ọ̀pẹ̀ / Dísẹ́ńbà | Oṣù Ọ̀pẹ̀ |
The word oṣù literally means "moon" (the celestial body), reflecting the lunar origin of month-counting. In modern usage, the English-derived names are far more common in everyday speech, especially in cities, while traditional names appear in literature, religious calendars, and academic prose.
Times of Day
Yoruba divides the day into named periods that align with daily routines.
| English | Yoruba |
|---|---|
| Morning | Òwúrọ̀ |
| Late morning | Òwúrọ̀ kùtùkùtù |
| Noon / midday | Ọ̀sán |
| Afternoon | Ọ̀sán gangan / Lẹ́yìn ọ̀sán |
| Evening | Ìrọ̀lẹ́ |
| Night | Òru |
| Late night / midnight | Ọ̀gànjọ́ òru |
| Dawn | Àfẹ̀mọ́júmọ́ / Àárọ̀ |
| Dusk | Ìrọ̀lẹ́ alẹ́ |
These time-of-day terms appear in standard greetings (see the Yoruba greetings reference). Ẹ káàárọ̀ is "good morning" (literally "may you greet the morning"), Ẹ káàsán is the noon greeting, and Ẹ kúùrọ̀lẹ́ is the evening greeting.
"Òwúrọ̀ ọjọ́ ni ọjọ́ ńyọ" — The morning of a day is when the day begins. The Yoruba proverb that morning sets the tone for everything.
Telling the Time
The traditional Yoruba system did not use clock-style hours. Time was reckoned by sun position, daily activities, and prayer times. Modern Yoruba time-telling uses a hybrid of borrowed numerals and Yoruba structural patterns.
| English | Yoruba |
|---|---|
| What time is it? | Àkókò wo ni? / Ìgbà wo ni? |
| Hour | Wákàtí / Àkókò |
| Minute | Ìṣẹ́jú |
| Second | Ìṣẹ́jú-àáyá / Sẹ́kíǹdì |
| O'clock | Ago |
| 1 o'clock | Ago kan |
| 2 o'clock | Ago méjì |
| 3 o'clock | Ago mẹ́ta |
| 7 o'clock | Ago méje |
| Half past | Aago + agogo + ààbọ̀ |
| 6:30 | Aago mẹ́fà ààbọ̀ |
| Quarter to | Iṣẹ́jú mẹ́ẹ̀ẹ́dógún sí |
| 5:45 | Iṣẹ́jú mẹ́ẹ̀ẹ́dógún sí ago mẹ́fà |
The word ago for "o'clock" is a borrowing (from English "o'clock" via Yoruba phonology). For in-depth discussion of how Yoruba constructs numbers (essential when stating any time), see the vigesimal system reference.
In casual speech, Yoruba speakers often switch to English numerals for clock time. Ago seven is more common than Ago méje in urban Lagos, even mid-Yoruba sentence.
Relative Time Expressions
Yoruba uses concise relative time markers that pack information English requires phrases for.
| English | Yoruba |
|---|---|
| Today | Òní |
| Yesterday | Àná |
| Day before yesterday | Ìjẹ́ta |
| Three days ago | Ìjẹ́rin |
| Tomorrow | Ọ̀la |
| Day after tomorrow | Òtùnla |
| Three days from now | Òtàrúnla |
| Now | Báyìí / Nísinsìnyí |
| Soon | Láìpẹ́ |
| Later | Lẹ́yìn |
| Already | Ti |
| Not yet | Kò tíì |
| Always | Nígbà gbogbo |
| Sometimes | Nígbà mìíràn |
| Never | Láé / Láéláé |
The progression àná (yesterday), ìjẹ́ta (two days ago), ìjẹ́rin (three days ago) extends in principle for several days, though five-or-more-days-ago is normally expressed by combining numerals: ọjọ́ márùn-ún sẹ́yìn ("five days behind").
Days, Weeks, Months, Years in Phrases
| English | Yoruba |
|---|---|
| Day | Ọjọ́ |
| Week | Ọṣẹ̀ |
| Month | Oṣù |
| Year | Ọdún |
| This week | Ọṣẹ̀ yìí |
| Last week | Ọṣẹ̀ tó kọjá |
| Next week | Ọṣẹ̀ tó ń bọ̀ |
| This month | Oṣù yìí |
| Last month | Oṣù tó kọjá |
| Next month | Oṣù tó ń bọ̀ |
| This year | Ọdún yìí |
| Last year | Ọdún tó kọjá / Èṣín |
| Next year | Ọdún tó ń bọ̀ / Àmọ̀dún |
The single-word forms èṣín (last year) and àmọ̀dún (next year) are more poetic and common in proverbs; the longer phrases dominate everyday speech.
Festivals and Time-Markers
Yoruba culture marks time partly by reference to traditional and religious festivals.
| Festival | Yoruba | Time |
|---|---|---|
| Yoruba New Year (Iwa Ji) | Ọdún Ọdún | Varies by lineage |
| Osun-Osogbo Festival | Ọdún Ọ̀ṣun | August |
| New Yam Festival | Ọdún Iṣu | Late summer / autumn |
| Ifa Festival | Ọdún Ifá | Varies |
| Eid al-Fitr (Muslim) | Ọdún Ìlẹ̀ya | Lunar |
| Christmas | Kérésìmesì | December 25 |
| Easter | Ọdún Àjíǹde | Spring |
"Ọdún tí a kò bá rí, ká dúpẹ́ pé a wá là á wo" — A festival we did not attend, let us be grateful we live to see [the next]. Time marked by festivals binds community memory.
Common Mistakes Learners Make
Confusing ọjọ́ (day) with ọjọ́ (rain): Both are spelled the same. Context disambiguates, but tone and surrounding words matter.
Mistranslating "next week" as "Ọṣẹ̀ tó wà": The correct form is Ọṣẹ̀ tó ń bọ̀ ("the week that is coming"). Tó wà would mean "that exists."
Using cardinal numbers without "ago": To say "1 o'clock," you say Ago kan, with the dedicated borrowed word ago. Saying kan alone in this context is unclear.
Forgetting that traditional month names exist: For poetic, religious, or formal writing, the indigenous month names (Ṣẹ́rẹ́, Èrèlè, Ẹrẹ̀nà) are preferred over English borrowings.
Confusing ọṣẹ̀ (week) with ọṣẹ́ (soap): The tones differ. Ọṣẹ̀ with low-low tones is "week"; ọṣẹ́ with low-high is "soap."

Frequently Asked Questions
Why does Yoruba have both traditional and English-borrowed month names? The Gregorian calendar arrived with Christian missionaries and British administration in the nineteenth century. Yoruba speakers preserved indigenous month names alongside the borrowed forms. In contemporary usage, the borrowed names dominate everyday speech while traditional names appear in literature, religious calendars, and ceremonial contexts.
What was the traditional Yoruba week like? A four-day market week, with each day dedicated to a particular orisha and a particular town's market. The word ọṣẹ̀ originally meant this four-day cycle and was repurposed for the seven-day Christian week.
Why is Sunday called Àìkú? The name means "no death" or "immortal" and was applied to Sunday at the time of Christian conversion. Some interpret it as referring to the resurrection (no death over Christ); others see it as a traditional Yoruba blessing applied to a sacred rest day.
Do Yoruba speakers actually use the four-day week today? Mostly in ritual and market contexts. Many traditional markets still rotate on a four-day cycle, so a town's "market day" repeats every four days in its old rhythm.
How do I tell time accurately in Yoruba? Use ago + numeral for the hour (ago méjì = 2 o'clock), then add ààbọ̀ for half-hour or ìṣẹ́jú + numeral + sí + ago for minutes-to constructions. Most casual speakers code-switch to English numerals.
What does ìjẹ́ta mean exactly? Two days ago, often translated "the day before yesterday." The series àná, ìjẹ́ta, ìjẹ́rin counts back precisely.
Are weekends important culturally? Increasingly yes, especially in Christian communities where Sunday (Àìkú) is reserved for worship and family. Saturday (Àbámẹ́ta) hosts most weddings, naming ceremonies, and social events.
