If you would like to enter multiple Google Calendar events without creating each one individually, create a CSV file of all your events, and then import that file into Google Calendar

I. Create CSV File

1. Create a .csv file with the following columns: Subject, Start Date, All Day Event, Start Time, End Time, Location, Description (if you prefer, download the csv file template and enter your own event details there)
   Important Guidelines:  https://support.google.com/calendar/answer/37118#advanced&zippy=%2Ccreate-or-edit-a-csv-file
   • Each event must be on a separate line of the spreadsheet
   • All-day events must be assigned the value "TRUE" in the "All Day Event" column
   • Non-All day events must be assigned the value "FALSE" in the "All Day Event" column and must have valid Start and End Time values (in 12-hour format, not military time)
   • Dates must be in the format MM/DD/YYYY
   • Be sure to save the file as a .csv file (not .xls)
     Sample .csv file filled out for 2 events to upload to Google Calendar
