Is my list uploaded anywhere?

No. The conversion runs in your web browser. Names and birth dates never leave your computer.

Do I need the year someone was born?

No. Dates like March 14, 3/14 or --03-14 (the style Google Contacts exports use) work without a year. When a year is given, it can be added to the event so you know which birthday it is.

What happens to February 29 birthdays?

They repeat on the last day of February: February 29 in leap years and February 28 in other years, so the birthday never disappears from your calendar.

How do the reminders work?

Choose a reminder at 9 AM on the day, the day before or a week before. Some calendar apps, Google Calendar in particular, may apply their own default notifications to imported events instead, so check your calendar's notification settings.

Where can I get a list of birthdays?

Export your contacts from Google Contacts or Outlook as a CSV file, which includes birthdays you have saved, or type a simple two-column list of names and dates in Excel or Google Sheets.

Birthday formats it understands

In your file	Read as
March 14	March 14, year unknown
1958-07-02	July 2, born 1958
--11-30	November 30 (Google Contacts style, no year)
2/29/1992	February 29, born 1992
Dec 25, 1990	December 25, born 1990

For day-first dates like 14/3/1985, choose "Day first" in step 2.

Tips

Import into a separate "Birthdays" calendar so you can give it its own color and share it with family.
Title wording. Change the event title to something like Call {name} or {name} turns another year older. {name} is replaced with each person's name.
Moving off Facebook. Facebook no longer gives a simple birthday calendar export, so a short spreadsheet typed from your friends list, converted here, is often the quickest way to keep the birthdays you care about.

Importing the calendar file

Google Calendar: on a computer, click the gear icon, choose Settings > Import & export, select the file and click Import. iPhone: open the file from Mail or Files and tap Add All. Outlook on the web: choose Add calendar > Upload from file.
