How to use Spanish clock time with “Es” and “Son” correctly

Introduction

Learning how to tell time in Spanish is one of the most practical skills for beginners. This article explains how to use Es and Son with clock time, step by step, with clear examples and tips for real conversations. By the end you will know when to say es, when to say son, and how to form common time expressions.

Basic rule: Es vs Son

The simplest rule is that you use Es with singular hours and Son with plural hours. Use Es for 1:00 only: Es la una. Use Son for all other hours: Son las dos, Son las tres, etc. This is because the verb refers to la hora (the hour), which is singular when the hour itself is one and plural for other numbers.

Examples of the basic rule

Es la una.

Son las dos.

Son las diez.

Forming full clock times

After establishing Es or Son, add the hour and then the minutes. Minutes are expressed with y for minutes past the hour and menos for minutes to the next hour. Use the 12-hour clock for conversational Spanish; specify mañana, tarde, or noche when needed.

Minutes past the hour: using y

To say minutes after the hour, use y followed by the number of minutes. Example: Son las tres y diez means 3:10. For 1:15 use the singular hour with Es: Es la una y cuarto. Quarter past and half past have special expressions: cuarto for 15 and media for 30.

Son las cinco y cinco.
Es la una y cuarto.
Son las siete y media.

Minutes to the hour: using menos

To express minutes before the next hour, use menos and the number of minutes remaining. For example, 4:50 becomes Son las cinco menos diez (five minus ten). For 1:45 use the singular form: Es la una menos cuarto is less common — native speakers prefer Es la una cuarenta y cinco or Es la una y cuarenta y cinco — however, you will often hear Es la una menos cuarto to mean 12:45 when speaking about the next hour from the perspective of the previous hour in certain regions; be attentive to context.

Son las nueve menos veinte.
Son las ocho menos cinco.

Special cases: noon and midnight

Noon and midnight are often expressed with specific words rather than numbers. Use mediodía for 12:00 PM and medianoche for 12:00 AM. When you want to be precise, you can still say Es mediodía and Es medianoche. These expressions use Es because they refer to a singular moment.

Es mediodía.
Es medianoche.

Using 12:00 with hours

If you prefer to use the hour construction, 12:00 can be said as Son las doce. Context will tell whether it is AM or PM; otherwise add de la mañana, de la tarde, or de la noche. For example: Son las doce de la noche for midnight, and Son las doce del mediodía or Son las doce del día for noon.

Son las doce de la mañana.
Son las doce del mediodía.

Using articles and gender agreement

Remember the structure: Es la for one o’clock because una is feminine (la una). For other hours use Son las since horas is plural and feminine. You will not use el or los in these constructions. The gender of the hour aligns with the feminine noun hora even though numerals themselves are not gendered in this context.

Es la una. Son las cuatro.

When talking about specific minutes and seconds

You can add minutos or segundos if you want to be explicit, though native speakers often omit them. For example, Son las dos minutos is unusual; instead say Son las dos y dos minutos or simply Son las dos y dos. When saying seconds in precise contexts, use segundos: Es la una, quince minutos y treinta segundos.

Son las cinco y veinte minutos.
Es la una, quince minutos y treinta segundos.

Common idiomatic expressions

Spanish has many time-related idioms where the literal grammar still follows the Es/Son rule. Learn these forms because they appear often in everyday speech.

Examples of idioms

Es hora de + infinitive means it is time to do something: Es hora de comer — It is time to eat.

Es la una exacta means it is exactly one o’clock.
Son las tres en punto means it is three sharp.

Using 24-hour vs 12-hour time

In written, formal, or timetable contexts Spaniards often use the 24-hour clock. When speaking, the 12-hour clock is far more common. If you use the 24-hour clock in speech, you will usually say the number with son if it is not one: Son las dieciocho horas is formal and uncommon in casual conversation, where you would say Son las seis de la tarde.

Son las dieciséis horas (formal timetable).
Son las cuatro de la tarde (conversational).

Regional differences and casual speech

Different Spanish-speaking regions have slightly different preferences. In some countries people often say the hour plus the minutes without using menos for times close to the next hour. In others, using menos is very common. Also, some speakers will say Es la una y cuarto for 1:15 while others prefer numeric minutes: Es la una y quince. Both are correct; understand regional variation and practice listening to native speech.

In Mexico you might hear more numeric forms, while in Spain you might hear tanto cuarto and media often. Both are fine for everyday use.

Politeness and asking the time

When asking someone for the time, common phrases combine the question with polite forms. Use ¿Qué hora es? for a general ask. Notice the inversion: the question uses the singular verb es even when the answer will use son because the structure is different. Native speakers respond with the full time using the correct Es or Son.

¿Qué hora es?
Son las tres y veinte.

Other useful question forms

¿A qué hora…? asks at what time something happens and uses the preposition a plus an infinitive or event: ¿A qué hora empieza la película? The response will include es or son depending on the hour.

¿A qué hora empieza la reunión?
Empieza a las nueve.

Practical tips for learners

1. Always memorize the rule: Es for 1:00, Son for everything else.
2. Practice common expressions like y cuarto, y media, and menos cuarto to sound natural.
3. Use de la mañana, de la tarde, de la noche to avoid confusion between AM and PM.
4. Listen to native speakers to pick up regional preferences for using menos or numeric minutes.
