Most of the United States went from Daylight Saving Time to Standard Time this past weekend, which means that my Sunday morning consisted of walking around the house adjusting the times on the clocks in the house. This is normally a chore that takes just a few minutes.
I spent an hour resetting the clock, going through the configuration process again, trying different Wi-Fi networks, resetting my phone, resetting my router, resetting my reset button, nothing worked.
One of my friends has an atomic clock. His problem is that the signal is poor in the room, so whenever the time changes, he has to unplug the clock, go to another room, plug it in, let it sync the time, and then move back to the original room.
On Windows 10, there's an app called "Alarms and Clock", but it doesn't have precision up to seconds, just minutes. I want an alarm at say 12:59:50PM, so 12:59PM with 10 seconds left. However, it can only do "12:59PM" which is not useful for my purpose.
I found a similar question on SuperUser ( -there-an-alarm-clock-app-for-windows-running-on-a-laptop), but it doesn't seem like those have seconds precision for my case. I also migrated this question from SuperUser to here because it was listed as off-topic there for software recommendations ( ).
I finally found a software that can do exactly as stated in the question. It is a free software for Windows called "Free Countdown Timer ( -countdown-timer.com/) by Comfort Software Group. Besides having seconds precision, it has the ability to do both manual start countdown timers as well as based on a date and other features such as repeating the alarm, custom sounds, etc.
Adjust the time and date settings as needed by typing into the "Date, Time:" box. You can also click the dropdown to adjust the time. Note that the software uses your computer's time, so if your computer's time is incorrect, you may experience an early or late alarm. Then click "OK".
Your alarm is now set. It is enabled the first you set it or when you adjust the settings. To start or stop the alarm, you have three options. Option one is to click the small checkbox to the left of the alarm. Option 2 is to right click on the alarm and select "Enabled". Option 3 is to select the alarm and then press "Ctrl + E". The third option is useful if you're not using a date countdown timer but a manual start countdown timer (where you start a non-date-based timer perhaps 1 minute before 12:59:50) since it is probably the fastest and more accurate way than fumbling around with your mouse with small dialog boxes.
Your countdown timer should be set. You can also back up your alarms using the software. I highly recommend using a website like to set your computer clock to the correct time. For Windows 10, I personally have issues with its automatic set time and date feature which often has accuracy issues of up to 1-2 min away from the universal clock time for stocks, websites, apps, etc. You'd have to set it manually in that case using your reaction time.
Here's an example: I started a new sandbox game and built a simple ship to get to Duna. Added an alarm in Kerbal Alarm Clock for the next Duna transfer and then headed to and played around a bit to get a slightly higher dV transfer that would give me an 80 day flight time. Here's the chosen transfer:
Similarly if I go by the transfer alarms in Kerbal Alarm Clock and try to do either manual maneuver nodes or use MechJeb to create them they just don't match up with the information. The Kerbal Alarm Clock windows are often 100s of days different from MechJeb's calculated nodes!
Many people nowadays don't own traditional clock radios or portable alarm clocks to take with them while travelling. While you can use your smartphone as an alarm clock, did you know that any Windows 10 device can also serve this purpose?
Yeah, that's right! The operating system comes with a built-in alarm clock app that you can set up with the following steps. This article will focus on how you can set up an alarm on a Windows 10 laptop.
4. You can configure additional settings like alarm sound, snooze time, number of repeats, and name of the alarm, but they are optional unless when needed. The essential step is to set the alarm time. Once done, click Save.
Setting an alarm on your Windows 10 device can be a convenient and practical way to ensure you wake up on time or stay on schedule throughout the day. With the built-in alarm clock app and simple settings adjustments, you can customize your alarm to suit your preferences and needs.
But, it's important to note that allowing your computer to stay awake indefinitely can impact its battery life, so it's important to balance the benefits of using the alarm with the need to preserve your device's battery.
I'm trying to create an alarm clock service via CMD Prompt. The service can be programmed to a certain time, and will play a song and ask a question before terminating. I'm running into two difficulties:
The tldr though would be the windows alarm is software. When the computer is shutdown, the software isn't running (like a alarm clock not having power). And thus, since the software isn't running, the alarm will not function when the system is shutdown.
Yes, some laptops can be started with a schedule in the bios. And if that is started a few minutes before the alarmgoes off, it might work. But then you run the risk of the computer starting up when you don't want it to. Possibly cooking itself to death in a bag or something.
Atomic Alarm Clock is a tool that has been designed to both change the dull look of the Windows desktop clock and to be used as an alarm clock that reminds you of important events and reminders using different sounds and icons.
Atomic Alarm Clock includes several different clock designs for your desktop, letting you customize each one of them to view the time with, or without seconds, with the date, using a countdown, or with the percentage of memory in use.
This program also displays the time for any of the time zones, activates programs, ends sessions, and restarts the computer when the alarm goes off, apart from its basic function of reminding you of an event or appointment using music and a pop-up window.
Atomic Alarm Clock is the best clock I've ever had for Windows. Unfortunately the clock does not work in Windows 11 Insider it is blocked from starting. Compatibility mode doesn't even help. If I want...
The easiest, fastest, and most convenient way to set an alarm on any computer is to use a free online alarm clock. All you need to use this alarm clock is an internet connection. You don't need to download an app.
You can use the default alarm clock app on mobile phones or download a free one from the App Store or Google Play Store. On iPhone, tap alarm at the bottom of the Clock app to set an alarm. Set a time, day, and frequency for the alarm.
The online alarm clock is a digital alarm clock you can use for free via your internet browser on any computer or mobile device. You can use the alarm to wake up in the morning and to help with daily routines like studying, exercising, cooking, or completing practice exams.
The online alarm clock simply runs via an internet connection. It's completely free, and you don't need to download any apps or software to use the internet alarm clock. Once you've set your alarm for your chosen time, the webpage will sound an alarm at the volume your computer is set. Make sure your volume is turned up to hear the alarm.
Once set, a live countdown will appear on-screen. You can end the alarm early by clicking Stop. Once the countdown hits zero, the alarm will sound. You can snooze the alarm for 10 minutes by clicking the Snooze button.
Finally, you can also view alarms you've previously set under Alarm Clock Data. Click Export to CSV to download the data or Clear Data to reset or forget the information. To set multiple alarms, open another tab and repeat the steps.
No, the online alarm clock only has a limited selection of pre-selected sounds. You can pick from several types of loud alarms, like a buzzer, bell, or white noise. Unfortunately, YouTube Music or Spotify links cannot be used for alarms.
Yes, this online alarm clock is loud and can be heard even if your computer's volume is low. The site uses your computer's volume to sound the alarm, so you can increase or decrease its volume using your computer's sound volume functions.
