iTunes (or Finder for macOS Catalina and later) can sync iPhone calendars to your Mac, but it does so by overwriting all the data, meaning it will replace the calendars on your Mac with the ones from your iPhone. Therefore, please make sure that the data on your Mac is backed up before using this feature.

Step 1. Open iTunes on your Mac (or Finder for macOS Catalina and later).
Step 2. Connect your iPhone to the Mac using a USB cable and unlock your iPhone.
Step 3. Click the device icon in the iTunes interface to go to the "Info" tab.
Step 4. Check the "Sync Calendars" option, then choose either "All calendars" or "Selected calendars".
Step 5. Click the "Apply" button to begin syncing your iPhone calendars to your Mac.

iCloud is the official syncing method provided by Apple, which automatically keeps your iPhone calendar in sync with your Mac without manual intervention. However, iCloud relies on an internet connection and may encounter synchronization issues. (How to free up iCloud storage?)
Here is how to sync iPhone and Mac calendar with iCloud:
Step 1. On your iPhone, open "Settings" and tap your "Apple ID" (the personal avatar at the top). Go to "iCloud" and, in the list of apps using iCloud, find "Calendars" and make sure its toggle is turned on.
Step 2. On your Mac, click the "Apple menu" in the top left corner > "System Settings" (for macOS Ventura and later) or "System Preferences" (for macOS Monterey and earlier).
Step 3. Select "Apple ID", then click "iCloud". In the iCloud options, ensure that "Calendars" is turned on.

Step 4. Make sure both your iPhone and Mac are connected to Wi-Fi. After a few minutes, your iPhone calendar data will automatically sync to the "Calendar" app on your Mac.
