Siden vi flyttede ind, har jeg skyndt mig mindre om morgenen.

Here siden means since. It introduces a starting point in the past and connects it to the present.

So Siden vi flyttede ind means Since we moved in.

This is different from for ... siden, which means ... ago: for to år siden = two years ago

It is also different from da, which usually just means when. Siden suggests that the situation in the main clause has been true from that past point until now.

Because vi flyttede ind refers to one completed event: the moment or period when the speakers moved into the place.

In Danish, after siden, it is very normal to use the simple past for the event that started the time period: Siden vi flyttede ind, har jeg ...

The main clause then uses the present perfect to describe something that has been true from that point up to now.

Yes. at flytte ind is a verb plus particle meaning to move in.

In Danish, these often work as a unit: at flytte ind = to move in

When the verb is finite, the particle often stays after it: vi flyttede ind

So flyttede ind should be understood together, not as two unrelated words.

Because Danish main clauses usually follow the V2 rule: the finite verb comes in the second position.

In this sentence, the whole opening clause Siden vi flyttede ind takes the first position. That means the finite verb har must come next, and the subject jeg comes after it:

Siden vi flyttede ind, har jeg skyndt mig mindre om morgenen.

If the sentence started with the subject, then you would get normal subject-verb order:

Jeg har skyndt mig mindre om morgenen siden vi flyttede ind.

Because the verb is at skynde sig, which is a reflexive verb.

English usually just says to hurry, but Danish uses a reflexive pronoun: jeg skynder mig du skynder dig han skynder sig vi skynder os

So mig is not optional here. It belongs to the verb expression.

Skyndt is the past participle of at skynde sig.

The present perfect in Danish is formed with har + past participle: jeg har skyndt mig

Compare: jeg skynder mig = present jeg skyndte mig = simple past jeg har skyndt mig = present perfect

So har jeg skyndt mig is just the normal perfect-tense form, with the word order changed because of the V2 rule.

Here mindre means less.

It modifies skyndt mig, so the idea is I have hurried less or I have been less rushed.

The comparison is understood from context: less than before they moved in. Danish does not need to add an explicit than before if that is already clear.

Not necessarily.

at skynde sig usually means to hurry or to rush. So skyndt mig mindre normally means that the speaker has been less rushed, has had less need to hurry, or has spent less time rushing.

It is more about being in less of a hurry than about literal physical speed.

Om morgenen is a common Danish expression meaning in the morning or in the mornings.

For general routines or repeated times of day, Danish often uses om + the definite form: om morgenen = in the morning / in the mornings om aftenen = in the evening / in the evenings

That is why it is morgenen and not just morgen here.

In this sentence, it means mornings in general.

The sentence describes a repeated pattern since moving in, so om morgenen is best understood as in the mornings or in the morning as part of my routine, not one single morning.

For one specific morning, Danish would usually use a different expression, such as i morges for this morning.

Because Siden vi flyttede ind is a subordinate clause placed before the main clause.

The comma marks the end of that opening clause and the start of the main clause: Siden vi flyttede ind, har jeg skyndt mig mindre om morgenen.

It helps show the structure clearly: first the time-setting clause, then the main statement.
