Dates, Years, and Decades

An ordinary Lebanese date puts the day before the month: خمسة تشرين الأول “the fifth of October.” The first day is special—أول أيار “May first”—but later days normally use cardinal numbers, not a full series of ordinals. Years are read as large numbers: ألفين وستة وعشرين “2026.”

This page teaches informal urban Lebanese calendar speech. Lebanon's traditional Levantine Gregorian month names are the production baseline. Pan-Arab month names, French or English code-switching, Hijri dates, and formal administrative phrasing are real, but they are labeled rather than blended into one invented system.

Day first, then month

For the first, use أول + month. From the second onward, use a cardinal day number followed directly by the month. An understood masculine يوم “day” helps explain masculine واحد/اتنين in 21 and 22.

English speakers may instinctively put the month first because of U.S. date speech. Lebanese normally leads with the day. The preposition بـ joins the date expression: بخمسة أيار “on May fifth.” نهار خمسة أيار is another transparent option when “on the day of” is useful.

The month names used in Lebanon

Lebanese daily life widely uses the Levantine month set below for the Gregorian calendar.

The formal spelling is often كانون الثاني، تشرين الثاني, with ث. Beirut speech normally says التاني, and this guide uses that readable colloquial spelling in Lebanese examples.

Cross-regional media and forms may instead show يناير، فبراير، مارس، أبريل، مايو، يونيو، يوليو، أغسطس، سبتمبر، أكتوبر، نوفمبر، ديسمبر (formal/cross-regional). Urban Lebanese professionals also code-switch to French or English month names (code-switching; audience-dependent). These are parallel naming systems, not evidence that one speaker “does not know Arabic.” Keep one system within an appointment unless you deliberately accommodate an audience.

Hijri month names serve religious and cultural dating and do not align one-to-one with Gregorian months. The calendar page covers coexistence of calendar systems.

Reading years as large numbers

Lebanese normally reads the year by its numerical chunks, not as two English-style pairs.

The conjunctions are structural: 2026 is ألفين وستة وعشرين, with و before the final compound. Reading “twenty twenty-six” is an English habit, not the default Lebanese formation.

Prepositions with dates and periods

Lebanese بـ covers many English on/in distinctions:

• بخمسة أيار — on May fifth;
• بآذار — in March;
• بسنة ألفين — in the year 2000;
• بالتسعينات — in the nineties.

For a range, use من ... لـ: من أول حزيران لآخر آب “from the beginning of June to the end of August.” Formal documents may introduce a date with بتاريخ “dated/on the date of” (formal/administrative).

Decades are plural period names

Lebanese forms decade labels with plural ـات: التمانينات “the eighties,” التسعينات “the nineties,” الألفينات “the two-thousands.” These name a period, not the exact year ending in eighty or ninety.

If the exact year matters, say it. بآخر التسعينات deliberately leaves several years possible; سنة ألف وتسعمية وتسعة وتسعين identifies 1999.

Written date formats and directionality

Lebanese forms commonly intend day/month/year, so ٥/١٠/٢٠٢٦ conventionally represents 5 October 2026 in that ordering. But slash dates are risky: U.S. readers may assume month/day, and bidirectional display can make Arabic-script context visually confusing.

When consequences matter, spell out the month. The right-to-left writing page explains why digits must not be manually reversed inside Arabic text.

Exact versus approximate date: a dialogue

Common Mistakes

Copying English month-first word order

Treating an ambiguous slash date as self-explanatory

Importing a formal ordinal date into casual speech

Keeping an English plural after a compound duration

Ignoring the construct form in a short duration

Key Takeaways

Say the day before the month, using أول only for day one and cardinals afterward. Use Lebanon's كانون، شباط، آذار... month series consistently, while recognizing pan-Arab and code-switched alternatives. Read years as descending large-number chunks, and use بـ for dates, months, years, and decades. Decade plurals are approximate periods; full years are exact. Spell out the month whenever a numeric format could be misread.
