๐งญ Step-by-Step Guide: Automate Birthday and Anniversary Reminders
๐น Step 1: Organize All Birthdays & Anniversaries
Start with creating a centralized Google Sheet like this:
Name | Occasion | Date | Phone Number | |
---|---|---|---|---|
Rahul Sharma | Birthday | 1990-08-12 | rahul@email.com | +91-9876543210 |
Neha Verma | Anniversary | 2015-12-25 | neha@email.com | +91-9876543211 |
-
Save the sheet in Google Drive and name it
Important Dates
.
๐น Step 2: Add Events to Google Calendar
You have two options here:
✅ Manual Add:
-
Open Google Calendar.
-
Create a recurring event (e.g., Rahul’s Birthday on August 12).
-
Set reminder time (e.g., 1 day before at 9 AM).
-
Add email or SMS notification.
✅ Auto-Add via Script:
Use Google Apps Script to auto-populate calendar events from the sheet.
function createCalendarEvents() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
var calendar = CalendarApp.getDefaultCalendar();
var data = sheet.getDataRange().getValues();
for (var i = 1; i < data.length; i++) {
var name = data[i][0];
var occasion = data[i][1];
var date = new Date(data[i][2]);
var title = `${name}'s ${occasion}`;
calendar.createAllDayEvent(title, date, {description: "Automated Reminder"});
}
}

๐น Step 3: Use Zapier to Automate Messaging
๐งฉ Zapier Workflow Example:
Trigger: Google Calendar event starts (e.g., Rahul’s Birthday)
Action 1: Send Email via Gmail (Template: "Happy Birthday, Rahul!")
Action 2: Send SMS via Twilio
Email Template:
Subject: ๐ Happy Birthday Rahul!
Body: Wishing you joy, health, and success. Have a great year ahead!
SMS Template:
"Hey Rahul! ๐ Just wanted to wish you a very Happy Birthday! - [Your Name]"
๐น Step 4: Use IFTTT for Voice Notifications
Want your smart speaker to remind you?
-
Use IFTTT applet: "If Google Calendar event starts, then say text via Google Assistant"
-
Example reminder: "Today is Neha's Anniversary. Don’t forget to call her!"
๐น Step 5: Automate via WhatsApp API (Optional)
If you use WhatsApp Business API, you can automate messages using Twilio + Templates.
WhatsApp Message Template:
Hello {{1}},
Wishing you a Happy {{2}}! ๐ Stay blessed.
Variables:
-
{{1}}
= Name -
{{2}}
= Birthday/Anniversary
Set up the automation through Twilio Studio Flow triggered by Google Calendar + Zapier.

---|---|
Personal Alert | 1 day before |
Email Wish | Same day (8 AM) |
SMS Wish | Same day (10 AM) |
WhatsApp Wish | Same day (11 AM) |
Gift Reminder | 3 days before |
๐ Pros and Cons of Automation
