Time, Dates & Schedules — I can tell and ask about time, dates, and schedules using common expressions.

Master the Greek expressions you need to navigate daily life, from telling time to making plans.

Historical Context & Motivation

The way we talk about time is deeply connected to how cultures have measured and valued it throughout history. In ancient Greece, people organized their lives around the ηλιακό ρολόι (sundial) and the movements of celestial bodies, long before mechanical clocks arrived. The Greek language evolved specific vocabulary and grammatical patterns to express time, dates, and scheduled events — many of which survive in Modern Greek today. Understanding this evolution helps you appreciate why certain expressions are structured the way they are.

~500 BCE
Ancient Greek Timekeeping
Ancient Greeks used sundials and water clocks (κλεψύδρα). They divided the day into twelve seasonal hours of varying length, influencing the vocabulary of time expressions still echoed in Modern Greek.
46 BCE
Julian Calendar Adoption
The Greek-speaking Eastern Roman Empire adopted the Julian calendar, which standardized month names. Many Modern Greek month names (Ιανουάριος, Φεβρουάριος) descend directly from this Latin-influenced system.
1923 CE
Greece Adopts the Gregorian Calendar
Greece officially switched to the Gregorian calendar, aligning its date system with most of Europe. The Greek Orthodox Church, however, still uses the Julian calendar for many religious observances.
Modern Era
Standardized Time in Everyday Greek
Today, Greeks use a 24-hour clock in official contexts (train schedules, news broadcasts) but commonly speak in a 12-hour format in conversation, adding π.μ. (πρωί/μεσημέρι) or μ.μ. (μετά το μεσημέρι) for clarity.

So why does this matter for you as a learner? Every time you catch a bus in Athens, make plans with a friend, or ask when a shop opens, you need to navigate Greek time expressions fluently. This lesson equips you with the grammar, vocabulary, and real-world phrases to do exactly that — from asking «Τι ώρα είναι;» (What time is it?) to reading a weekly schedule and describing your own routine.

Core Principles & Key Vocabulary

Before diving into full sentences, you need a solid grasp of the building blocks. Greek time expressions rely on a few core principles: the use of the feminine article with ώρα (hour), cardinal and ordinal numbers in their feminine forms, and specific prepositions that signal when something happens. Let's lay out these foundations clearly.

1

Η ώρα (The Hour)

The word ώρα is feminine, so numbers and articles that accompany it must be in their feminine form. For example, «η μία» (one o'clock), «οι δύο» (two o'clock).
2

Και, Παρά, Μισή, Τέταρτο

Και means 'and' (minutes past). Παρά means 'minus' (minutes to). Μισή = half, τέταρτο = quarter.
3

Days & Months as Vocabulary Sets

Greek days of the week (η Δευτέρα, η Τρίτη…) are feminine nouns. Months (Ιανουάριος, Φεβρουάριος…) are masculine. Learning their gender is essential for correct article and preposition use.
4

Prepositions of Time

Use στις + hour for 'at' a time, τη/την + day for 'on' a day, and τον/το + month for 'in' a month.
5

Asking vs. Telling

To ask time: «Τι ώρα είναι;» To ask when: «Πότε;» or «Τι ώρα…;» To answer, use «Είναι…» for current time, and «στις…» for scheduled events.
KEY TAKEAWAY
Think of Greek time expressions like building with LEGO bricks. The hour is your base piece, και/παρά is the connector piece that tells you which direction (past or to), and the minutes snap on at the end. Once you know which piece goes where, you can build any time expression you need.

Visual Explanation — The Greek Clock

This clock face shows the Greek numbers for each hour, with the right half labeled ΚΑΙ (minutes past) and the left half labeled ΠΑΡΑ (minutes to the next hour). The example reads «Είναι μία και δέκα» — It is 1:10.

Notice the key rule: when the minute hand is on the right side of the clock (from 12 going clockwise to 6), you use και to add minutes past the hour. When the minute hand crosses to the left side (from 6 up to 12), you switch to παρά and subtract minutes from the upcoming hour. This mirrors the English pattern of saying 'ten past one' versus 'ten to two,' but in Greek, the split happens precisely at the half-hour mark. At the bottom of the clock, you use «και μισή» (and a half), and at the quarter points, you say «και τέταρτο» or «παρά τέταρτο».

How Greek Time Expressions Work

Sentence Formulas for Telling Time

CURRENT TIME (PAST THE HOUR)
Είναι + [HOUR] + και + [MINUTES]
Example: Είναι τρεις και είκοσι = It is 3:20. The hour uses the feminine form of the number.
CURRENT TIME (TO THE HOUR)
Είναι + [NEXT HOUR] + παρά + [MINUTES]
Example: Είναι τέσσερις παρά δέκα = It is 3:50 (lit. 'four minus ten'). You name the upcoming hour, then subtract.
SCHEDULED TIME ('AT')
στις + [HOUR] (+ και/παρά + [MINUTES])
Example: Το μάθημα αρχίζει στις εννιά και μισή = The class starts at 9:30. Use στις for all scheduled events.
SPECIAL CASE — 1:00
Είναι η μία / στη μία
One o'clock uses the singular feminine article «η» and the singular form «στη» (not «στις»), because «μία» is singular. All other hours (2–12) use the plural «στις».

Dates: Day + Month + Year

Greek dates follow a predictable order: the day (as a cardinal number), then the month (in the genitive case), then the year. For example, «15 Μαρτίου 2025» reads as «δεκαπέντε Μαρτίου, δύο χιλιάδες είκοσι πέντε.» The month shifts to the genitive case (Μάρτιος → Μαρτίου), which signals possession or association — literally 'the fifteenth of March.' To say 'on' a specific date, use «στις» + the number: «στις 15 Μαρτίου.»

⚠️ Watch Out!
The first day of the month uses the ordinal «πρώτη» (first), not the cardinal number. So January 1st is «η πρώτη Ιανουαρίου» — not «μία Ιανουαρίου.» After the 1st, all other dates use cardinal numbers: «δύο Ιανουαρίου,» «τρεις Ιανουαρίου,» etc.

Days, Months & Time Vocabulary

Days of the Week — Note that Saturday (Σάββατο) is neuter, while the rest are feminine.
Ημέρα (Day)GreekPronunciation Hint
Mondayη Δευτέραee dhef-TEH-rah
Tuesdayη Τρίτηee TREE-tee
Wednesdayη Τετάρτηee teh-TAR-tee
Thursdayη Πέμπτηee PEMP-tee
Fridayη Παρασκευήee pah-rah-skeh-VEE
Saturdayτο Σάββατοtoh SAH-vah-toh
Sundayη Κυριακήee kee-ree-ah-KEE
All twelve Greek months (note the masculine -ος/-ιος endings) alongside essential time-of-day words. The months shift to the genitive case (-ου/-ίου) when used in dates.

A quick mnemonic: the first four days of the week (Δευτέρα through Πέμπτη) come from the Greek ordinal numbers for second through fifth (δεύτερος, τρίτος, τέταρτος, πέμπτος), because Sunday was traditionally considered the first day. Παρασκευή means 'preparation' (originally for the Sabbath), Σάββατο derives from the Hebrew 'Shabbat,' and Κυριακή means 'the Lord's day.' Knowing these origins makes the words much easier to remember.

Worked Example — Reading & Creating a Schedule

Imagine you're an exchange student in Thessaloniki. Your host family gives you a weekly schedule for activities. Let's work through reading it and then creating sentences about your own plans.

Scenario: Your Weekly Schedule in Thessaloniki
1
Step 1 — Read the schedule entryThe schedule says: «Δευτέρα — Μάθημα ελληνικών, 9:30 π.μ.» You need to express this aloud. Start by identifying the day: Δευτέρα = Monday. The time is 9:30, which is 'nine and a half.'
Τη Δευτέρα, το μάθημα ελληνικών είναι στις εννιά και μισή το πρωί.
2
Step 2 — Ask about a different dayYou want to ask your host family: 'What time is the movie on Friday?' Build the question using Τι ώρα (what time) + the event + the day. Remember to use «την Παρασκευή» with the accusative article for 'on Friday.'
Τι ώρα είναι η ταινία την Παρασκευή;
3
Step 3 — Respond with a time using 'παρά'Your host says the movie is at 7:45 p.m. Since 45 minutes is past the half-hour mark, you express this as 'eight minus a quarter.' Use «στις» because it's a scheduled event, and add «το βράδυ» for 'in the evening.'
Η ταινία είναι στις οχτώ παρά τέταρτο το βράδυ.
4
Step 4 — State a dateYour friend asks when your birthday is. The date is March 22. Use «στις» + the number + the month in the genitive case. Μάρτιος → Μαρτίου.
Τα γενέθλιά μου είναι στις είκοσι δύο Μαρτίου.
5
Step 5 — Combine day, time, and date in one sentenceNow put it all together. You want to say: 'The concert is on Saturday, June 10th, at 8:30 in the evening.' Layer the elements: day → date → time → time of day.
Η συναυλία είναι το Σάββατο, δέκα Ιουνίου, στις οχτώ και μισή το βράδυ.

Formal vs. Informal Time Expressions

Just like in English, Greek speakers shift between formal and informal registers when discussing time. A train schedule announcement sounds very different from a text message to a friend. Understanding both registers prepares you for real conversations and official interactions.

Comparing formal and informal time expressions in Greek
FeatureFormal / OfficialInformal / Conversational
Clock format24-hour: «στις 20:30» (είκοσι και τριάντα)12-hour: «στις οχτώ και μισή το βράδυ»
MinutesAlways stated numerically: «δεκατέσσερις και σαράντα πέντε»Uses και/παρά, μισή, τέταρτο
ContextAnnouncements, timetables, newsFriends, family, casual talk
Example«Η πτήση αναχωρεί στις 15:45.»«Θα φύγουμε στις τέσσερις παρά τέταρτο.»
DatesFull form: «15 Μαρτίου 2025»Short form: «στις 15 Μαρτίου» or just «στις 15»
KEY TAKEAWAY
Think of formal vs. informal Greek time like GPS directions vs. a friend giving directions. The GPS says 'proceed 2.4 kilometers north on National Road 7' — that's the 24-hour, precise official style. Your friend says 'go up the road about 10 minutes until you see the big church' — that's the conversational και/παρά style. Both get you there, but you need to know which one fits the situation.

Connecting to Advanced Scheduling & Subordinate Clauses

Once you're comfortable with basic time expressions, you can start building more complex sentences that describe routines, set conditions, and coordinate events. This is where time expressions connect to broader Greek grammar — specifically subordinate clauses using words like όταν (when), πριν (before), αφού (after), and μέχρι (until).

From basic to advanced time sentences
Basic ExpressionAdvanced Expression
Το μάθημα αρχίζει στις 9.Όταν αρχίζει το μάθημα στις 9, πρέπει να είμαι έτοιμος.
Θα φάμε στις 2.Πριν φάμε στις 2, θα τελειώσω τα μαθήματά μου.
Η ταινία τελειώνει στις 10.Αφού τελειώσει η ταινία στις 10, θα πάμε για παγωτό.
Θα περιμένω.Θα περιμένω μέχρι τις 5 το απόγευμα.

Notice how the advanced examples embed time expressions within larger sentence structures. The conjunction όταν (when) introduces a temporal subordinate clause, while πριν (before) takes a subjunctive verb form (πριν φάμε, not πριν τρώμε). These patterns will become central as you advance into Greek narrative and descriptive writing. For now, focus on mastering the base time expressions — they're the foundation everything else builds on.

Practice Problems

PROBLEM 1CONCEPTUAL
Explain in your own words: why does Greek use «παρά» (minus) for times after the half hour, and what is the next hour rule? Give an example using 4:50.
PROBLEM 2BASIC
Translate the following times into Greek: (a) 3:15, (b) 6:30, (c) 11:45, (d) 1:00.
PROBLEM 3INTERMEDIATE
Your Greek friend texts you: «Θα πάμε σινεμά την Τετάρτη στις εφτά και τέταρτο το βράδυ.» (a) What day and time is the movie? (b) Write a response saying you'll arrive at 7:00 p.m., and ask what date it is.
PROBLEM 4APPLIED
You are planning a trip to Crete and need to read this ferry schedule: «Πειραιάς → Ηράκλειο: Αναχώρηση 21:00, Άφιξη 05:30. Δρομολόγια: Δευτέρα, Τετάρτη, Παρασκευή.» Write three sentences in Greek explaining the schedule to a friend who doesn't read Greek, using conversational (12-hour) time.
PROBLEM 5CRITICAL THINKING
Compare how Greek and English handle the concept of 'quarter to' and 'half past.' Then consider: if a Greek speaker says «Είναι δύο παρά είκοσι,» what time is it? Could this expression cause confusion for an English speaker who expects 'twenty to two' to be 1:40? Explain the potential miscommunication and how context helps.

Summary — Time, Dates & Schedules in Greek

You can now tell time in Greek using the formula Είναι + hour + και/παρά + minutes, remembering that και adds minutes past the hour (up to :30), while παρά subtracts minutes from the next hour (after :30). The special terms μισή (half) and τέταρτο (quarter) replace the numbers 30 and 15 in conversation. For scheduled events, always use στις + hour to say 'at' a specific time, except for 1:00, which takes the singular στη μία.

For dates, Greek follows the order day (cardinal number) + month (genitive case) + year. The days of the week are mostly feminine nouns derived from ordinal numbers, while months are masculine and shift to the genitive (-ου/-ίου) in dates. You can ask about time with «Τι ώρα είναι;» and about dates with «Τι ημερομηνία είναι σήμερα;» Formal contexts use the 24-hour clock, while casual conversation uses 12-hour time with π.μ. / μ.μ. or time-of-day words like «το πρωί» and «το βράδυ.»
