The time button is on the left side of your Tamagotchi, and you hold it down to enter time-setting mode

Most Tamagotchi models use the same method: press and hold the left button (marked A on some versions) for about three seconds until the display shows a clock icon or the hour starts blinking. Once you're in time-setting mode, the left button moves you forward through the hours, the middle button (B) moves you forward through the minutes, and the right button (C) confirms your selection and moves to the next setting. The exact sequence depends on which Tamagotchi generation you own, but the principle is identical across all current models.

If your Tamagotchi is a newer color model like the Tamagotchi Nano or Tamagotchi Uni, the buttons work the same way but the screen will show the time more clearly as you adjust it. Older black-and-white models display the time as a two-digit number that cycles through 00 to 23 (24-hour format). You'll know you've finished setting the time when the clock icon disappears and your Tamagotchi returns to the normal screen.

Key Takeaways

  • Hold down the left button for three seconds to enter time-setting mode on any Tamagotchi model.
  • Use the left button to change hours, the middle button to change minutes, and the right button to confirm each step.
  • Tamagotchi uses 24-hour time format, so 13:00 is 1 p.m. and 00:00 is midnight.
  • You may need to reset the time if your Tamagotchi's battery dies or if you replace the battery.

Why the time matters on a Tamagotchi

The time you set controls when your Tamagotchi gets hungry, sleepy, and sick. If you set the time incorrectly, your pet will behave as though it's a different time of day than it actually is — it might demand food at 3 a.m. or go to sleep at noon. This doesn't harm your Tamagotchi, but it makes the device harder to live with if you're trying to keep it on a schedule that matches your own life.

The time also determines when your Tamagotchi enters "sleep mode" at night. Most models go dormant around 9 p.m. and wake up around 9 a.m., though this varies by model. If you set the time wrong, your Tamagotchi will sleep during the day when you want to interact with it, or stay awake all night when you're trying to sleep.

Step-by-step time setting for the most common models

Original Tamagotchi and Tamagotchi Nano: Hold the left button until you see a clock icon. The hour will blink. Press the left button to increase the hour (it cycles from 00 to 23). Press the middle button to move to minutes. Press the left button again to increase minutes by one. Press the right button to confirm and exit.

Tamagotchi Uni and color models: Hold the left button until the time display appears on screen. The hour field will be highlighted. Use the left button to move forward through hours and the right button to move backward. Press the middle button to confirm and move to minutes. Repeat the process for minutes, then press the middle button one more time to save and exit.

Tamagotchi Nano (pocket-sized version): This model uses the same three-button system but the display is smaller. Hold the left button until you see the clock. The process is identical to the original Tamagotchi — left button for hours, middle button to advance to minutes, left button again for minutes, right button to confirm.

What to do if you can't find the time-setting mode

If holding the left button doesn't show a clock icon, your Tamagotchi may already be in a different mode. Press the right button to exit whatever screen you're on, then try again. Some models require you to be on the main screen (showing your pet) before you can access time settings.

If you've just replaced the battery or your Tamagotchi has been without power for a while, it will automatically prompt you to set the time the next time you turn it on. You'll see a clock icon and blinking numbers — this is the same time-setting mode, just triggered automatically instead of manually.

If your Tamagotchi is frozen or not responding to button presses, remove the battery for 30 seconds, then reinsert it. This will reset the device and prompt you to set the time again. You won't lose your pet or its progress — the reset only clears temporary glitches.

Changing the time after you've already set it

You can change the time at any point by holding the left button again. This is useful if you travel to a different time zone or if you realize you set it incorrectly. The process is identical to the first time you set it — hold left, adjust hours and minutes, confirm with the right button.

Some players change the time deliberately to shift when their Tamagotchi sleeps or eats, especially if they want to interact with it at different times of day. This is a normal use and won't damage the device. Just remember that your Tamagotchi will behave according to the time you've set, not the actual time on your phone or clock.

Common mistakes when setting Tamagotchi time

The most common error is holding the left button for too long and cycling past the time you want. The hour counter moves quickly and wraps around from 23 back to 00. If you overshoot, keep pressing left — it will cycle all the way around. Alternatively, on newer color models, you can press the right button to move backward instead of forward.

Another frequent mistake is forgetting that Tamagotchi uses 24-hour time. If you want to set it to 2 p.m., you need to enter 14, not 2. The device won't accept 14:60 for minutes or 25:00 for hours — if you try to go past the maximum, it will wrap back to 00.

Some players accidentally press the middle button too many times and end up confirming the time before they've finished adjusting the minutes. If this happens, just hold the left button again to re-enter time-setting mode and correct it.

Frequently Asked Questions

Does my Tamagotchi lose the time if the battery dies?

Yes. When you remove the battery or it runs out of power, the time resets to 00:00. When you put in a new battery, your Tamagotchi will prompt you to set the time again. Your pet's progress and evolution are saved separately, so you won't lose your Tamagotchi itself — only the time setting.

Can I set the time to a 12-hour format instead of 24-hour?

No. All Tamagotchi models use 24-hour time (military time) only. There is no setting to switch to 12-hour format. You'll need to do the conversion yourself: add 12 to any p.m. time (so 3 p.m. becomes 15:00) and use 00:00 for midnight.

What happens if I set the time wrong on purpose?

Your Tamagotchi will behave according to the time you set, not the real time. It will get hungry, tired, and sick based on that false time. This won't break the device, but it can make your pet harder to care for if the schedule doesn't match your actual day. You can change it back anytime by holding the left button again.

Do I need to set the time every time I turn my Tamagotchi on?

No. Once you set the time, it stays set as long as the battery is in the device. You only need to reset it if the battery dies, you replace the battery, or you deliberately want to change what time your Tamagotchi thinks it is.
