Birthday Calendar — Reminders & Notifications

About

🎂 Birthday calendar that remembers so you don't have to

Birthday calendar is a simple Chrome extension that keeps every birthday in one place and sends a reminder notification automatically, right inside your browser. No more awkward "happy birthday, sorry it's late" messages, no more digging through old chats trying to recall a birth date. Add a name once and the birthday calendar takes care of the rest.

Most people track birthdays with sticky notes, phone contacts, or plain memory instead of a real birthday calendar. That works fine until a busy week makes a birthday slip by quietly. This birthday calendar extension solves that by living right next to your other browser tools — always one click away, always watching the dates for you.

📅 How it works

1. Click the extension icon and the birthday calendar opens instantly in the Chrome side panel.
2. Pick any date on the birthday calendar to add a new entry — name, day, month, and an optional birth year.
3. The birthday calendar calculates age automatically and shows it next to every upcoming birthday.
4. Notifications appear on their own: three days before, one day before, and on the day itself.
5. A badge on the icon shows how many birthdays are coming up today, so you get a glance at what's ahead.

✨ Why people pick this birthday calendar

➤ Clean birthday calendar view — see the whole month at once, with a small dot marking every saved date.
➤ Smart reminder system — get notified three days early, one day early, and on the day, with zero setup.
➤ Automatic age calculator — add a birth year once and the age updates every following year on its own.
➤ Color-coded urgency — each birthday's color shifts from green to red as the date gets closer, so the most urgent ones stand out at a glance.
➤ Lightweight side panel — it opens in Chrome's native side panel and never covers the page you're browsing.

🔔 Reminder notifications, done right

The reminder engine runs quietly in the background. You don't have to open the extension or remember anything yourself — it checks the dates every day and fires a notification only when it matters:

- 3 days before a birthday, so there's time to plan a gift or a card.
- 1 day before a birthday, as a final heads-up.
- On the day itself, so a message goes out on time.

Each notification type can be switched on or off independently in the settings tab, so the reminders fit the way you actually want to be nudged — some people want all three, others just want the same-day alert.

🎈 Built for people who track a lot of dates

A birthday calendar like this becomes genuinely useful once you have more than a handful of birthdays to remember — family, close friends, coworkers, clients. Instead of a paper planner or a reminder app on your phone you forget to open, this birthday calendar keeps everything visible the moment you need it, right in Chrome.

Selecting a date instantly shows every birthday saved for that day, while a separate "upcoming" section lists what's next, sorted by how soon it's coming, with the same color-coded urgency carried through every card. Easy to scan, whether you're checking one date or just want to see who's next.

📌 What you can do inside the birthday calendar

1️⃣ Add unlimited birthdays — names, dates, and optional birth years, with no limit on how many you store.
2️⃣ Edit anytime — click any saved birthday to update the name, date, or birth year in place.
3️⃣ Export and import — back up your saved birthdays to a JSON file and restore them later, or move them to another device.
4️⃣ Customize reminders — choose exactly which notifications you want to receive.
5️⃣ Sync across devices — optionally turn on sync in settings to carry your birthday calendar to every device signed into the same Chrome account.

🔒 Privacy by default

This birthday calendar extension is built around one simple rule: your data stays yours. By default, everything is stored locally on this device only — there's no account to create and no server involved. If you'd like the same birthday calendar on another device, sync is one toggle away in settings; until then, nothing leaves your browser. There's no analytics and no tracking, ever.

💡 A few tips

▸ Add birth years whenever you know them, so the age calculator stays accurate every year without extra work.
▸ Use the export option once your list grows, just to keep a backup copy somewhere safe.
▸ Click directly on a saved birthday card to edit it — no need to delete and re-add.
▸ Turn on sync in settings if you use Chrome on more than one device and want the same birthday calendar everywhere.

🎁 Never miss a birthday again

Whether it's a parent, a partner, a close friend, or a colleague, this birthday calendar always makes sure the date never sneaks up on you. Add it once, and the reminders take care of remembering every single year after that. No clutter, no required account — just a clean birthday calendar that quietly does its job in the background of your browser.

Install the birthday calendar extension, add your first few important dates, and let the automatic reminders handle the rest.
