Prohlídka je v pondělí.

Prohlídka can mean several related things depending on context:

• a tour: a guided visit, for example of a building or museum
• a viewing: for example of an apartment or house
• an inspection / examination: in some contexts, a check or look-over

So the exact English translation depends on the situation. In this sentence, prohlídka is the subject and is a feminine noun.

In standard Czech, je is the 3rd person singular of být (to be) and it is normally expressed in the present tense:

• Prohlídka je v pondělí. = The tour is on Monday.

Unlike some languages, Czech usually does not omit the present-tense verb to be in normal statements like this. So Prohlídka v pondělí would sound incomplete in standard Czech.

This is just a difference in how the two languages express time.

In Czech, days of the week are commonly used with v:

• v pondělí = on Monday
• v úterý = on Tuesday
• ve středu = on Wednesday

So even though English uses on, Czech uses v here.

Here pondělí is in the locative case, because the preposition v often takes the locative when it means in / on in expressions of place or time.

So:

• v + locative
• v pondělí = on Monday

This is a very common pattern with days of the week.

Because some Czech nouns do not visibly change in certain cases.

Pondělí is a neuter noun, and in this form the nominative singular and locative singular are the same:

• nominative: pondělí
• locative: pondělí

So the case changes grammatically, but the word form stays the same.

No, Czech word order is relatively flexible.

Prohlídka je v pondělí is a normal, neutral sentence. But you could also say:

• V pondělí je prohlídka.

Both are correct, but the emphasis shifts slightly.

• Prohlídka je v pondělí. → neutral, focusing on the fact about the tour/viewing
• V pondělí je prohlídka. → puts more focus on Monday

Czech word order often reflects information structure and emphasis more than strict grammatical necessity.

Czech has no articles, so it does not have direct equivalents of a / an / the.

That means prohlídka can mean:

• a tour
• the tour
• a viewing
• the viewing

The exact meaning is understood from context.

No. In Czech, days of the week are normally not capitalized.

So you write:

• v pondělí
• v úterý
• ve středu

This is different from English, where Monday, Tuesday, etc. are capitalized.

A rough pronunciation guide is:

• Prohlídka ≈ proh-HLEET-kah
• je ≈ yeh
• v pondělí ≈ f PON-dyeh-lee

A few useful notes:

• ř is not present here, so nothing unusually difficult in that sense
• í is a long vowel, so say it longer in prohlídka and pondělí
• v is often pronounced more like f before a voiceless consonant, so v pondělí may sound closer to f pondělí

Not with the same meaning.

• v pondělí means on Monday
• na pondělí usually suggests something like for Monday rather than on Monday

For example:

• Prohlídka je v pondělí. = The viewing is on Monday.
• Je to naplánované na pondělí. = It is scheduled for Monday.

So for a simple statement about when something happens, v pondělí is the natural choice.

Yes, prohlídka is feminine. You can tell partly from the ending -a, which is very common for feminine nouns.

It matters because adjectives, pronouns, and sometimes past-tense forms would have to agree with it. For example:

• Ta prohlídka je v pondělí. = That tour/viewing is on Monday.
• Prohlídka byla v pondělí. = The tour/viewing was on Monday.

In your sentence, the gender does not strongly affect the visible form of je, but it is still part of the noun’s grammar.
