Days of the week in English: Monday to Sunday with pronunciation

English is the world’s most widely used lingua franca. According to Ethnologue’s 2024 data, nearly 1.5 billion people speak it as a first or second language. The names of the days are one of the first things an English learner needs, schedules, meeting planning, email, and social media all rely on these words.

English day names combine two sources: Germanic mythology (Norse gods) and the Roman planetary system. This makes them both special and memorable. Monday (Moon’s day) and Sunday (Sun’s day) refer directly to celestial bodies. Tuesday, Wednesday, Thursday, and Friday preserve the names of Germanic gods, Tyr, Woden, Thor, and Frigg. Saturday is a direct descendant of the Latin planet name Saturnus.

"The names of the days in English preserve a fascinating blend of Roman planetary tradition and Germanic theological replacement, a linguistic fossil of two cultures meeting."

(David Crystal, The Cambridge Encyclopedia of the English Language, 3rd edition, 2019)

This guide goes through each day with pronunciation, etymology, and cultural context, so you can use them confidently in English.

Days of the week in English, table

Monday, Monday

Monday comes from Old English Mōnandæg (Moon’s day). The Moon, moon, marks the first day of the week in English, like in most Germanic languages. In English, Monday points to the Moon, so the logic is celestial.

Pronunciation tip: stress the first syllable, MUN-day, not “mon-DAY”. Many learners stress the second syllable, which sounds unusual to native ears.

Tuesday, Tuesday

Tuesday comes from Old English Tīwesdæg. Tyr (also spelled Tiw) was the Germanic god of war, one of the oldest figures in the Norse tradition. The Latin equivalent was Mars’s day (dies Martis), which is why Romance languages have forms like martedi, mardi, martes.

Pronunciation: TYOOZ-day. The “TUE” letter group surprises many learners. It is not “too-ez-day”, it is closer to “tyooz-day”, especially in British English.

Wednesday, Wednesday

Wednesday comes from Old English Wōdnesdæg, Woden’s day (the Scandinavian Odin). Woden is the chief god in Germanic mythology, linked to wisdom, war, and the dead. The “d” kept in spelling is silent, which makes this word a famous trap for English learners.

Thursday, Thursday

Thursday comes from Old English Þūnresdæg, Thor’s day. Thor, the god of thunder and lightning, is one of the most popular figures in Germanic mythology. The Latin equivalent was Jupiter’s day (dies Iovis), the two gods filled a similar role in myth.

Pronunciation challenge: the “Th” sound /θ/. Put your tongue just behind your upper teeth and breathe out. THURZ-day. It can sound a bit like an “s” to learners, but you make it with the tongue between the teeth. This is one of the hardest sounds for many learners.

Friday, Friday

Friday comes from Old English Frīgedæg, Frigg’s (or Freya’s) day. Frigg was Odin’s wife, a goddess linked to fertility and love. The Latin dies Veneris (Venus’s day) marked the same role, both goddesses connect to love and beauty.

Friday has a special role in English-speaking culture: the end of the workweek, and the start of fun and social life. The English expression TGIF (Thank God It's Friday, “Thank God it’s Friday”) became one of the most quoted workplace slogans.

Saturday, Saturday

Saturday is the only day whose name comes directly from a Latin planet name: Saturnus. The Old English form was Sæternesdæg. Unlike the other Germanic day names, no Germanic god replacement happened here, Saturnus stayed in English.

Spanish and Italian sábado and sabato, by contrast, come from Hebrew Shabbat. This shows that English and the Romance languages reached the same day through different cultural paths.

Sunday, Sunday

Sunday comes from Old English Sunnandæg (Sun’s day). The Sun, sun, is the center of the solar system, and in prehistory it was the most important celestial body. Latin dies Solis (Sun’s day) was the original, which Christian reform changed to dies Dominica (the Lord’s day), Romance languages kept that (dimanche, domingo, domenica).

Abbreviations and calendars

In English calendars and schedules, days often appear in abbreviated form. You should know these for emails, calendar apps, and media.

Useful phrases with days

In English, using days has a few grammar habits that differ from many other languages. The key point: English does not add endings like “on Monday” through inflection. Instead, it uses the preposition “on”.

“This Monday” vs. “next Monday”, an important difference

For many learners, the difference between this Monday and next Monday can feel unclear. Native English speakers often understand it like this:

• This Monday = the nearest upcoming Monday (if it’s Sunday, then tomorrow)
• Next Monday = the Monday after that (one week later)

This can vary by region and context. If you want to be sure, add the date: “Monday the 10th”, this removes any ambiguity.

“On Monday” vs. “on Mondays”, one-time vs. regular

In English, the singular (on Monday) points to one specific Monday. The plural (on Mondays) points to a regular, repeated event.

Cultural differences

TGIF, Thank God It's Friday

TGIF (Thank God It's Friday, “Thank God it’s Friday”) is one of the most common English cultural references. It has been part of pop culture since the 1970s. It became a symbol of English-speaking work culture. You will hear it in movies, series, office emails, and social media. The TGI Fridays restaurant chain also takes its name from this expression.

Black Friday

Black Friday (Black Friday) is the Friday after Thanksgiving in the United States. It is the biggest shopping day each year in the United States. The term has spread globally, and most online stores in Hungary use it too. If you browse ads in English in late November, you will definitely see this phrase.

Weekday in English: weekday and workday

In English, weekday (a non-weekend day) and workday (a working day) are two slightly different ideas. Weekday runs from Monday to Friday. Workday more often points to your actual working hours. Business day specifically means days when businesses and offices are open.

Days in sentences

The table below shows how English day names appear in natural sentences. This helps you understand word order and the use of the preposition “on”.

Pronunciation challenges

For many learners, English day names cause regular difficulty in two areas: the silent “d” in Wednesday and the /θ/ sound in Thursday.

In English, every day name ends with “-day”. This comes from Old English dæg (day), and it stayed in all Germanic languages. In German it is -tag (Montag, Dienstag...), in Dutch it is -dag (maandag, dinsdag...), all the same root. This parallel can help you remember the days if you know other Germanic languages.
