Contemporary Filipino uses several numeral traditions for time. Spanish-derived ala-una, alas-dos, alas-tres are deeply established for clock hours; native numbers are natural for durations such as dalawang oras “two hours”; English readings are common in digital, workplace, and code-switched settings. Good usage means choosing a coherent form for the domain, not forcing one system everywhere.
Core clock forms
| Function | Typical form | Example |
|---|---|---|
| one o'clock | ala-una | ala-una ng hapon |
| other hours | alas- + Spanish-derived number | alas-siyete ng umaga |
| digital minutes | hour plus minutes | alas-otso kinse |
| approximate time | bandang + clock time | bandang alas-dos |
| duration | native number + linker + unit | dalawang oras |
| range | mula… hanggang… | mula alas-nuwebe hanggang alas-onse |
Standard edited spelling uses a hyphen in ala-una and alas-dos. Unhyphenated alas dos is widespread in informal messages, but this guide follows the KWF-oriented standard.
The clock expressions belong to a broader set of Spanish-derived numbers in everyday use. Their survival does not make the whole sentence Spanish: Filipino markers, predicates, and particles continue to organize the clause.
Magsisimula ang klase nang alas-otso ng umaga.
The class will begin at eight in the morning. (neutral)
Bandang alas-singko ng hapon tayo aalis para hindi mainit.
We will leave around five in the afternoon so it will not be hot. (neutral)
Ng umaga, ng hapon, and ng gabi disambiguate the twelve-hour clock. In schedules, 24-hour notation is also common: 18:30 is unambiguous in formal timetables even if speakers read it in English or with Spanish-derived numbers.
Minutes, halves, and contemporary variation
Digital-style readings that omit y are common, as in alas-dos kinse for 2:15. In standard written Spanish-derived combinations, y appears after a form not ending in e, as in alas-singko y beynte, but is omitted after e, as in alas-siyete treynta for 7:30. Y medya “and a half” remains widely understood in conversational clock time: alas-dos y medya. English seven thirty or nine fifteen is frequent in code-switched offices and schools (code-switched), but it should be labeled rather than presented as the only Filipino pattern.
Alas-dos y medya ako pupunta sa dentista.
I am going to the dentist at two thirty. (neutral conversational clock expression)
Alas-siyete treynta ang huling biyahe ng bus.
The last bus trip is at seven thirty. (neutral contemporary reading)
Native descriptive alternatives such as ikapito at kalahati ng gabi are interpretable but sound formal or pedagogical beside everyday alas-siyete y medya. Multiple systems coexist, but mixing pieces randomly—such as alas-seven—is unmarked only in code-switching.
Scheduling and duration
Use sa or adverbial nang with a time point according to construction, and mula…hanggang… for a range. A duration behaves as a measure phrase and requires the numerical linker.
Bukas ang klinika mula alas-nuwebe ng umaga hanggang alas-singko ng hapon.
The clinic is open from nine in the morning until five in the afternoon. (neutral)
Dalawang oras ang pulong, kaya magdala ka ng tubig.
The meeting lasts two hours, so bring water. (neutral)
Apat na oras kaming naghintay dahil naantala ang biyahe.
We waited for four hours because the trip was delayed. (neutral)
Dalawa ends in a vowel and takes attached -ng: dalawang oras. Apat ends in t, so it takes separate na: apat na oras. English plural hours does not cause plural marking on oras.
Calendar time versus elapsed time
A clock point answers anong oras? “at what time?” A duration answers gaano katagal? “for how long?” Keep these roles distinct even when English uses time for both.
Gaano katagal ang biyahe? — Mga tatlong oras kapag walang trapiko.
How long is the trip? — About three hours when there is no traffic. (informal conversation)
Anong oras darating ang tren? — Alas-onse kinse ayon sa iskedyul.
What time will the train arrive? — Eleven fifteen according to the schedule. (neutral)
Mga tatlong oras is approximate because mga precedes the numeral. By contrast, alas-onse kinse is a clock reading, not an eleven-hour duration. This distinction prevents literal English transfers such as using alas- before a duration.
Questions, punctuality, and changes
Anong oras ka libre sa Huwebes?
What time are you free on Thursday? (informal conversation)
Hindi na tuloy ang pulong sa alas-tres; inilipat ito sa alas-kuwatro.
The three o’clock meeting is no longer going ahead; it was moved to four. (neutral)
For exact formal announcements, sa ganap na alas-diyes means “at exactly ten.” In ordinary conversation, eksaktong alas-diyes is common but reflects an English-derived adjective; ganap na is a readily available neutral Filipino choice.
A short exchange
— Puwede ka ba bukas ng alas-dos? — May klase ako hanggang alas-dos y medya. Alas-tres na lang.
— Are you available tomorrow at two? — I have class until two thirty. Let’s make it three instead. (informal conversation)
The final na lang selects the revised option. Repeating a full clause is unnecessary because the scheduling task is understood.
Common Mistakes
1. Using plural morphology on the time unit
❌ Tatlong orases ang biyahe.
Incorrect — oras does not take an English- or Spanish-style plural ending after a number.
✅ Tatlong oras ang biyahe.
The trip takes three hours. (neutral)
2. Omitting the numerical linker
❌ Dalawa oras ang pagitan ng mga biyahe.
Incorrect — dalawa must link to oras.
✅ Dalawang oras ang pagitan ng mga biyahe.
The trips are two hours apart. (neutral)
3. Using the ordinary plural marker with an exact duration
❌ Mga dalawang oras ang pulong.
Wrong if exactly two hours is intended—mga before a numeral means approximation.
✅ Dalawang oras ang pulong.
The meeting lasts two hours. (exact)
4. Mixing clock systems unintentionally
❌ Magkita tayo ng alas-seven thirty.
Uncontrolled code-switching in an otherwise Filipino clock phrase.
✅ Magkita tayo nang alas-siyete treynta.
Let’s meet at seven thirty. (neutral contemporary Filipino)
Key Takeaways
- Spanish-derived ala-/alas- forms dominate everyday clock hours.
- Native numerals are natural for durations and require linkers: dalawang oras, apat na oras.
- English digital readings are common but code-switched; keep one system coherent for the context.
- Use bandang for approximation and mula…hanggang… for ranges.
