Use Google Calendar on both phones, or a shared calendar that opens from a link. Apple only shares private iCloud calendars "with other iCloud users", so the Android person can view an iCloud calendar at most, never add to it.
Google works if both of you are fine with a Google account. If the iPhone person does not want one, a browser-based calendar works on both phones with no account at all.
Opens in the browser on iPhone and Android. No app, no account.
Apple's own help page says private sharing is for iCloud users: on iCloud.com, "invitees must have an Apple Account and use iCloud in order to use the calendar." Someone on Android without an Apple Account cannot join, so the invitation goes nowhere useful.
Apple's fallback is Public Calendar, which makes "a read-only version that anyone can view but not change." That is fine for a class schedule. For a partner, roommate or family member who needs to add plans, it is a dead end.
Google Calendar has apps for iPhone and Android, and a shared Google calendar shows up in both. This is the most common answer, and it works well when both people already have a Google account.
Two details trip people up. Creating a new calendar only works in a browser on a computer. Sharing it afterwards works in the phone apps: Menu, Settings, pick the calendar, then under "Shared with" tap Add people or groups. The other person has to click the link in Google's email before the calendar appears for them.
If the iPhone owner wants to stay on iCloud, they can turn on Public Calendar and send the link. The Android person adds it in Google Calendar on a computer under Add other calendars, From URL. Google says you cannot subscribe by URL in its phone apps.
The result is view only, and anyone with the link can see it. Use it for a schedule you want the other person to see, not for a calendar you plan together.
TimeTree runs on iPhone and Android and is built for sharing, with chat on each event. Everyone needs the app and an account. Its free plan is ad-supported; Premium is $4.49 a month or $44.99 a year as a subscription.
Cozi is aimed at running a family, with lists and meal plans next to the calendar. Its free calendar only shows a 30-day window with ads, and Cozi Gold is $39 a year.
A browser calendar sidesteps iPhone versus Android entirely, because both phones have a browser. With Junto you create the calendar, send the link in your usual chat, and the other person types their first name. Nobody makes an account or installs anything.
Each person can also add the calendar's sync link to the calendar app they already use: Add Subscription Calendar on iPhone, From URL in Google Calendar on a computer. The sync is one way, so you add shared plans on the shared calendar and they appear in both phones' calendars.
All four work across both phones. The difference is what each person has to set up and whether everyone can add plans.

It is not a replacement for your phone's own calendar. There is no two-way sync, so a plan you add in Google or Apple Calendar does not appear on the shared calendar. There is no chat on events (TimeTree has that) and no lists or meal plans (Cozi has those).
If both of you already use Google every day, Option 1 is simpler. The link option is for the households where one person will not make a Google account, or where you also want friends or family on the same calendar.
Opens in the browser on iPhone and Android. No app, no account.
Only as a read-only copy. Turn on Public Calendar for an iCloud calendar and send the link; they can add it to Google Calendar on a computer with From URL. They cannot add or change events. For a calendar you both edit, use Google Calendar on both phones or a link calendar such as Junto, which opens in any browser.
If you both have Google accounts, a shared Google Calendar is the simplest, because Google has apps for both phones. If someone will not make an account, Junto opens from a link in any browser with only a first name. TimeTree works on both phones too, with chat, but everyone installs the app and signs up. Choose by what each person already uses.
Yes. Share it with their email, they click the link in Google's email, and the calendar appears in the Google Calendar app on their iPhone. They need a Google account for that. If they do not have one, Junto gives the two of you a shared calendar they open from a link with just their first name, no account required.
Yes, but not through iCloud, because private iCloud calendars are shared with iCloud users only. Mixed families usually pick Google Calendar, which needs a Google account for each person, or a calendar everyone opens from a link. Junto is one of those: one link for the whole family, any phone, first names only, free up to 8 members.
Yes. Google Calendar has a website, but it still needs a Google account. Junto runs entirely in the browser on both phones, with no app and no account: the person creating it sends a link, everyone else types a first name. You can save it to your home screen from the browser so it opens like an app.
Yes, for a calendar that publishes a sync link. In the Calendar app tap Calendars, Add Calendar, then Add Subscription Calendar and paste the link. It is read-only on the iPhone side. Junto provides that link on every calendar, so its shared plans appear next to your own events, and you add new plans on the shared calendar itself.
Because only iCloud users can edit a privately shared iCloud calendar, and an Android phone is not on iCloud. The public link is view only by design. To plan together, move the shared plans to a calendar you both can edit: Google Calendar if you both have accounts, or Junto if you want one link that needs no account.
Google Calendar and iCloud sharing are free. TimeTree has a free plan with ads and a Premium subscription at $4.49 a month or $44.99 a year. Cozi's free calendar is limited to a 30-day window. Junto is free for private calendars up to 8 members, then a one-time $4.99 plus tax, with no subscription.
