La fecha de reincorporación sigue a las vacaciones anuales.

In this sentence, seguir a means to come after or to follow something in sequence.

So:

• La fecha de reincorporación sigue a las vacaciones anuales = The return-to-work date comes after the annual holidays

The a is required here because the verb is being used with that meaning of following something.

Be careful: seguir can mean different things in different contexts:

• Seguir estudiando = to keep studying / continue studying
• Seguir a alguien = to follow someone
• Seguir a algo in a sequence = to come after something

So in this sentence, a las vacaciones anuales is the thing that the date follows.

Reincorporación refers to returning to a job, post, or normal duties, especially after an absence such as holidays, sick leave, maternity leave, or a break.

In workplace Spanish, it is a fairly formal noun. Here, fecha de reincorporación means:

• date of returning to work
• return date
• date of rejoining

It comes from the verb reincorporarse, which often means to return to work / rejoin.

Examples:

• Me reincorporo el lunes. = I return to work on Monday.
• La reincorporación será en septiembre. = The return will be in September.

Spanish often uses noun + de + noun structures where English might use a compound noun or a more verbal expression.

So:

• fecha de reincorporación literally = date of reincorporation
• natural English = return-to-work date or return date

This structure is very common in Spanish:

• fecha de nacimiento = date of birth
• permiso de trabajo = work permit
• horario de oficina = office hours

You could express the idea in other ways, such as fecha para reincorporarse, but fecha de reincorporación sounds more standard and formal in administrative or HR language.

Spanish uses the definite article much more often than English.

So La fecha de reincorporación is perfectly normal Spanish, even where English might simply say Return date in a heading or label.

Using la makes it a complete noun phrase:

• la fecha = the date

Spanish often includes the article with general or known items where English might omit it. For example:

• La reunión es mañana. = The meeting is tomorrow.
• El trabajo empieza a las ocho. = Work starts at eight. / The work starts at eight.

In an isolated sentence like this, La fecha de reincorporación sounds natural and complete.

In Spanish, vacaciones is normally used in the plural when talking about a holiday period or time off.

So:

• las vacaciones = the holidays / vacation

This is one of those cases where Spanish and English organize the idea differently. English often uses singular vacation, but Spanish usually uses plural vacaciones.

Examples:

• Estoy de vacaciones. = I’m on holiday / on vacation.
• Después de las vacaciones, volvemos al trabajo. = After the holidays, we go back to work.

Using singular vacación is much less common and usually not what you want in everyday Peninsular Spanish.

In Spanish, adjectives usually come after the noun.

So:

• vacaciones anuales = annual holidays

This is the normal word order:

• reunión anual = annual meeting
• informe mensual = monthly report
• permiso temporal = temporary leave

Putting the adjective before the noun is sometimes possible in Spanish, but it often changes the tone, emphasis, or sounds literary. Here, vacaciones anuales is the standard and natural order.

Anuales means annual, so it specifies that these are the regular yearly holidays, not just any time off.

Without anuales, las vacaciones simply means the holidays / vacation in general.

With anuales, the sentence sounds more formal and specific, like HR, legal, or administrative language:

• vacaciones = holidays / vacation
• vacaciones anuales = annual leave / annual holidays

So this wording suggests the standard yearly entitlement rather than, for example, sick leave or a special absence.

Because adjectives in Spanish must agree with the noun they describe.

Here:

• vacaciones is feminine plural
• so the adjective must also be feminine plural
• therefore: anuales

Agreement examples:

• vacación anual = singular
• vacaciones anuales = plural
• permiso anual = masculine singular
• reuniones anuales = feminine plural

This is a key feature of Spanish grammar: adjectives match nouns in gender and number.

Yes. Sigue is the third person singular present of seguir.

The subject is la fecha, which is singular, so:

• yo sigo
• tú sigues
• él/ella sigue
• la fecha sigue

The present tense is used because the sentence is stating a fact or schedule relationship: the return date follows the annual holidays.

This kind of present is common in formal descriptions, policies, timetables, and administrative language.

Yes. Even if the meaning is already known, it helps to see how Spanish structure does not always map directly onto English.

Possible natural translations include:

• The return-to-work date follows the annual holidays.
• The return date comes after the annual holidays.
• The date of returning to work is after the annual leave period.

The most literal version is not always the most natural English version. For example, reincorporación often needs a smoother English phrase like return to work or rejoining depending on context.

It sounds fairly formal, especially because of fecha de reincorporación and vacaciones anuales.

A more everyday way to express a similar idea might be:

• La vuelta al trabajo es después de las vacaciones. = The return to work is after the holidays.
• Te reincorporas después de las vacaciones. = You return to work after the holidays.

The original sentence sounds like something you might read in:

• an HR document
• a company email
• an official notice
• administrative paperwork

So it is good useful Spanish, but on the more formal side.

Yes, and that would often sound more straightforward.

For example:

• La fecha de reincorporación es después de las vacaciones anuales.

This also means that the return date is after the annual holidays.

The difference is mostly one of style:

• sigue a = follows / comes after, a bit more formal or structured
• es después de = is after, simpler and very clear

Both are correct, but sigue a gives the sentence a slightly more formal, administrative tone.
