As an Android expert, I am familiar with the process of syncing calendars between two Android phones. Here are the steps to do it:

1. **Make sure both phones are signed in to the same Google account.** This is the account that you use to access the Google Play Store and other Google services.

2. Open the Calendar app on both phones.
3. **Tap the menu icon in the top-left corner of the screen.**

4. Tap "Settings".

5. Tap "Accounts".
6. **Make sure that the same Google account is selected on both phones.**
7.
Tap the "Sync**" button on the phone that you want to sync the calendar from.**
8.
Tap the "Sync now**" button on the phone that you want to sync the calendar to.**

Your calendars should now be synced between the two phones. Any changes that you make to the calendar on one phone will be automatically reflected on the other phone.
