Preparing Your Google Sheets Data

Before you can create a calendar from your spreadsheet, you need to ensure your data is correctly structured. Google Calendar supports specific data formats, including date, time, and descriptions. Here's how to format your data:

1. **Date Column**: The first row should contain the event title (e.g., Meeting, Deadline), and the second row should contain the date in a recognizable format (e.g., 2022/03/15). Subsequent rows should contain the dates for each event.

Formatting Date Column

Google Calendar recognizes dates in various formats, such as yyyy/mm/dd, mm/dd/yy, or dd-mm-yyyy. Ensure consistency across your entire dataset.

2. **Time Column**: If you have specific start and end times for your events, include these in the adjacent columns, formatted as hh:mm (24-hour format) or hh:mm AM/PM.

Adding Time Zones

If your events span different time zones, you can include a 'Time Zone' column with three-letter International Organization for Standardization (ISO) time zone abbreviations (e.g., PST, EST, GMT).
