How to Change the Time on a Tamagotchi (All Major Versions)

Tamagotchis have been around since 1996, and while the core concept hasn't changed — you're keeping a digital pet alive — the hardware has gone through several distinct generations. Each one handles time-setting a little differently. Knowing which version you have is the first thing that determines how this process actually goes.

Why the Time Setting Matters on a Tamagotchi

Your Tamagotchi's internal clock directly controls your pet's daily cycle. Sleep times, hunger rhythms, and even certain evolution triggers are tied to the time of day. If the clock is off — whether because of a battery swap, daylight saving time, or a reset — your pet's behavior will feel misaligned. It might "sleep" in the middle of the afternoon or be wide awake at 2 AM, which disrupts care routines and can affect long-term outcomes for your pet.

Getting the time right isn't cosmetic. It's functional.

The Two Button Types You'll Work With

Before jumping into steps, it helps to understand the physical controls. Tamagotchi devices typically use either:

• Three physical buttons (A, B, C) — common on the original vintage units, the Tamagotchi Connection series, and many modern re-releases
• A combination of buttons and a touchscreen — found on the Tamagotchi Smart and Tamagotchi Uni

The method for adjusting time varies significantly between these two input styles.

How to Change the Time on Vintage and Connection-Era Tamagotchis 🕐

For the original 1996/1997 Tamagotchi, Tamagotchi Connection (V1–V6), and the Tamagotchi Mini, the process is straightforward:

1. Press the middle button (B) to access the main menu
2. Navigate to the clock icon using the left (A) or right (C) button
3. Press B to select it
4. Use A to increment the hours, B to confirm and move to minutes
5. Adjust minutes the same way, then confirm to save

On some versions, you may need to hold A and C simultaneously to access a settings or clock menu directly — bypassing the main menu entirely. This shortcut is particularly common on Connection-era devices.

Important: On units with a small reset pinhole on the back, pressing that button will wipe all data, not just the time. Use the menu method above, not the reset pin, when you only want to update the clock.

How to Change the Time on the Tamagotchi On and Tamagotchi Meets

The Tamagotchi On (international version) and Tamagotchi Meets (Japanese version) introduced a more structured menu system with icon-based navigation:

1. Press the middle button to open the main menu
2. Navigate to the Settings icon (wrench or gear symbol, depending on version)
3. Select Clock or Time
4. Use the left/right buttons to adjust hours and minutes
5. Confirm each value with the center button

These units also allow AM/PM toggling if you're using a 12-hour format. Some regional versions default to 24-hour time, so the display format you see may differ from what you expect.

How to Change the Time on the Tamagotchi Smart and Tamagotchi Uni

The Tamagotchi Smart and Tamagotchi Uni are the most modern devices and use touchscreen-forward interfaces:

1. Tap the menu icon on the home screen
2. Navigate to Settings
3. Select Date & Time or Clock Settings
4. Swipe or tap to adjust hours, minutes, and the date
5. Confirm to apply

The Tamagotchi Uni also supports app connectivity via Bluetooth, and in some configurations the time may sync or need to be verified after pairing with the companion app. If your Uni's time resets after a connection session, check whether app-synced time settings are overriding your manual input.

What Happens After a Battery Change

Replacing the battery almost always resets the clock, and on older models it may reset the entire device. On newer units like the On and Uni, some save data is preserved through a brief battery swap if done quickly — but the clock typically still needs to be re-entered manually.

If you're doing a planned battery swap, note the time beforehand so you can re-enter it immediately. On original vintage units, a reset will restart your pet from an egg, so timing the swap carefully matters.

Factors That Affect How This Works for You 🔋

The steps above cover the main versions, but several variables shape how smooth this process actually is for any given user:

• Which generation you own — the single biggest factor. The button layout and menu depth differ meaningfully across versions.
• Regional variant — Japanese and international versions of the same device sometimes have different menu structures or language displays that affect navigation
• Battery state — a low battery can cause clock drift or cause the unit to behave erratically during time-setting
• App connectivity — on Smart and Uni devices, whether you're using the companion app adds a layer that can interact with manual time settings
• Whether the unit has been reset — a freshly reset device will walk you through time-setting during initial setup, which is a different flow than adjusting it mid-use

The specific version sitting in your hands — and its current state — is what ultimately determines which of these paths applies to you.
