What you'll learn

  • Build a fully automated birthday reminder system using Google Sheets, Apps Script, and Gmail from scratch
  • Create and structure a Google Sheet as a simple database to store names, dates, relationships, and notes
  • Write and understand JavaScript code in Google Apps Script without any prior programming experience
  • Explain what variables are and how to use them to store and reference information in a script
  • Use functions to organise code into reusable blocks that perform specific tasks
  • Apply for loops to iterate through spreadsheet data and process multiple rows automatically
  • Implement if statements to make decisions in code based on conditions such as matching dates
  • Work with JavaScript date objects to compare today's date against stored birthday data accurately
  • Send automated emails programmatically using Google's built-in MailApp service
  • Access and read Google Sheets data from within a script using the SpreadsheetApp object
  • Set up a time-driven trigger that runs a script automatically every day at a scheduled time

Description

Have you ever forgotten an important birthday and felt terrible about it?

You are not alone. With busy lives, large families, and endless social circles, it is almost impossible to keep track of every important date. What if you could build a system that automatically reminds you the day before and on the actual day — every single year — without you ever having to think about it again?

That is exactly what you will build in this course.

What you will create:

In this hands-on micro course, you will build a fully automated birthday reminder system using three free Google tools — Google Sheets, Google Apps Script, and Gmail. The system stores your birthday list in a simple spreadsheet, checks it every morning at 8am, and sends you a personalised email alert automatically. Because it runs entirely in Google's cloud, it works 24 hours a day, 7 days a week — even when your computer is completely switched off.

Set it up once. Let it run forever.

No coding experience required:

Every single line of code is explained in plain English. You do not need to know JavaScript, programming, or anything technical before starting this course. If you can use a basic spreadsheet and send an email, you have everything you need to complete this project and have it running by the end of the course.

What makes this course different:

This is not a theory course. There are no abstract programming concepts or lengthy lectures about syntax rules. Every module is focused entirely on building the real working project. You will understand what each line of code does and why, but the goal is always a finished, deployed, fully functional system — not just notes.

What you will learn:

You will learn how to structure a Google Sheet as a simple database, write and understand JavaScript functions, work with date comparisons, send emails programmatically, and deploy a cloud-based time-driven trigger that runs automatically every day. These are real, transferable skills you can apply to countless other automation projects beyond this course.

Who this course is for:

This course is ideal for complete beginners, busy professionals, Google Workspace users, small business owners, and anyone who wants to start automating everyday tasks without hiring a developer or spending any money.

Enrol today and never miss a birthday again.

Who this course is for:

  • This course is perfect for you if: You are someone who wants to use technology to simplify and automate everyday tasks but have no programming background and do not know where to start. You have heard terms like automation, cloud computing, and Apps Script but they feel intimidating or out of reach. This course proves they are not.
  • You are a complete beginner who has never written a single line of code but is curious about what coding can do in real life. Rather than learning programming theory in the abstract, you want to build something real, useful, and immediately practical that you will actually use every day.
  • You are a busy professional, parent, or individual who juggles a large social and family circle and wants a reliable system to make sure you never miss an important birthday again. You want technology to do the remembering for you.
  • You are a Google Workspace user — someone who already uses Gmail, Google Sheets, or Google Drive in their daily life and wants to unlock the hidden automation power that already exists inside those tools for free.
  • You are a small business owner, freelancer, or entrepreneur who wants to start automating repetitive tasks and sees this project as the perfect first step into the world of business automation without hiring a developer.
  • You are a student or career changer looking to add practical automation and basic scripting skills to your portfolio or CV, and you want a beginner-friendly project you can point to as real evidence of your ability.
  • You are a Udemy learner who enjoys project-based courses — you learn best by doing rather than watching theory lectures, and you want to finish a course with something working and deployable, not just notes.
