No período de experiência, bato ponto todos os dias.

Yes. No is a contraction of em + o:

• em = in / on / at
• o = the (masculine singular)

So:

• em o período → no período

This kind of contraction is very common in Portuguese:

• em + a → na
• em + os → nos
• em + as → nas

So No período de experiência literally means something like In the probationary period or more naturally During the probation period.

Literally, yes, it looks like period of experience, but in Brazilian Portuguese this expression commonly means a trial period or probationary period at a job.

So in work-related contexts:

• período de experiência = probation period
• contrato de experiência = probationary contract / trial contract

This is a good example of where a word-for-word translation can sound strange in English even though the Portuguese expression is perfectly normal.

Portuguese often leaves out the subject pronoun when the verb ending already makes the subject clear.

Here:

• bato = I hit / I punch / I clock in
• the ending -o shows it is eu (I)

So:

• Eu bato ponto todos os dias.
• Bato ponto todos os dias.

Both are correct, but the second is very natural because Portuguese is a pro-drop language, meaning subject pronouns are often omitted when they are obvious from the verb.

Bato is the 1st person singular present form of bater.

Basic meaning of bater:

• to hit
• to beat
• to knock

But in the expression bater ponto, it is an idiom related to work attendance. It means:

• to punch the clock
• to clock in
• sometimes more broadly to register your working hours

So:

• bato ponto = I clock in / I punch the clock

This is a very common thing in Portuguese: a verb keeps its basic meaning in some contexts, but in a fixed expression it gets a more specific idiomatic meaning.

In Brazil, bater ponto means recording your work time in a formal system, traditionally by using a time clock.

Depending on context, it may mean:

• to clock in
• to clock out
• to punch the clock
• to register attendance/hours

For example:

• Eu bato ponto às 8. = I clock in at 8.
• Todo funcionário precisa bater ponto. = Every employee has to clock in/register their hours.

So in your sentence, bato ponto todos os dias suggests a regular work routine of officially recording attendance every day.

Both are correct in Brazilian Portuguese.

• todos os dias = every day
• todo dia = every day

The version with todos os dias can sound a little more explicit or slightly more formal, while todo dia is very common in everyday speech.

Examples:

• Estudo todos os dias.
• Estudo todo dia.

Both mean I study every day.

So in this sentence, todos os dias is completely natural.

That is just how Portuguese normally expresses this idea.

Portuguese often uses:

• todo dia or
• todos os dias

English usually says:

• every day

Even though English uses singular and Portuguese may use plural, the meaning is the same: something happens on a daily basis.

So don’t translate the structure too literally. Just learn todos os dias as a standard expression meaning every day.

Yes. Durante o período de experiência is also correct.

Comparison:

• No período de experiência = in / during the probation period
• Durante o período de experiência = during the probation period

Both are natural.
A small nuance:

• No período de experiência is a bit more compact and very common.
• Durante can sound slightly more explicit.

So the original sentence is perfectly natural, but Durante o período de experiência, bato ponto todos os dias would also work.

Here it describes a habitual action, not necessarily something happening right now.

In Portuguese, the simple present often covers both:

• actions happening regularly
• general truths
• habits

So:

• Bato ponto todos os dias. = I clock in every day.

This is similar to English simple present for routines:

• I work
• I study
• I drive to work every day

If you wanted to emphasize something happening right now, Portuguese would often use:

• estou batendo ponto
  but that would sound unusual in this specific context unless you really mean the action is in progress at that moment.

By itself, ponto often does mean point, but it has several meanings depending on context.

Common meanings include:

• point
• dot
• period/full stop
• bus stop (in ponto de ônibus)
• work attendance/time record in expressions related to employment

In bater ponto, ponto refers to the employee time record or time clock system, not a geometric point.

So this is another case where the literal meaning of an individual word is less important than the fixed expression.

Yes, it sounds natural and idiomatic in Brazilian Portuguese.

It has:

• a normal time-expression opener: No período de experiência
• a very common workplace expression: bato ponto
• a standard routine phrase: todos os dias

A Brazilian speaker would understand it as something like:

• During my probation period, I clock in every day.
• During the trial period, I punch the clock every day.

So this is a good, real-life sentence for workplace Portuguese.
