(Date)Windows 11中的日期和时间格式设置(Time Format Settings)
您可以在Windows 11中更改六种设置：
- 日历：Windows 使用公历作为默认日历，全球许多国家现在都在使用它（这是提供的唯一选项）。Windows 11 允许您显示两个附加日历 - 简体中文和繁体中文 - 通过在(Chinese—by)日期(Date)和时间 >附加(Additional)设置
下的任务栏中选择不显示附加日历。
- 一周的第一(First)天：将(Set)一周中的任何一天设置为日历中的第一天。通常，人们更喜欢Monday或Sunday。
- 短日期：短日期格式是指日期的全数字 dd/mm/yy 版本（例如，06/18/2022）。短日期设置提供了多种数字格式，具体取决于您喜欢首先出现日、月还是年。您还可以更改是否要使用斜线或破折号显示日期。
- 长日期：这是指日期的书面版本。此设置允许您选择是否也显示日期（例如，星期三(Wednesday)）。
- 短时间(Short)：此设置将时间显示为代表小时和分钟的一系列简短数字（例如，上午 11:24）。短时间格式有三种变体。要更改为 24 小时格式，请选择短时间(Short)并选择不显示 AM 或 PM 的数字。
- 长时间：除了小时和分钟外，还会显示秒（例如，上午 11:24:36）。此设置提供与短时间相同的变化。
您还可以向任务栏添加额外的时钟(additional clocks to your taskbar)。这在与不同时区的同事或家人交流时很有用。为此，请打开Settings > Time和语言 >日期(Date)和时间 >附加(Additional)时钟。
如何在Windows 10中更改(Windows 10)日期(Date)和时间格式(Time Format)
在Windows 10中，该过程或多或少是相同的：
- 按(Press)Windows + I 打开设置应用(Settings)程序。
- 选择时间和语言。
- 在左侧菜单中，选择日期(Date)和时间格式选项卡。
- 在右上角的边栏中，选择日期(Date)、时间和区域格式。
- 在区域设置的底部，选择更改(Change)数据格式。
- 在这里，您可以访问上述相同的设置。
注意：与Windows 11一样，您可以右键单击日期和时间选项卡并选择调整(Adjust)日期/时间以更改时间和日期格式。您还可以通过控制面板(via the Control Panel)访问这些设置。为此，请打开Control Panel > Clock和Region > Date和时间(Time)。
个性化是关键
您总是需要查看您的桌面，因此按照您的喜好准确格式化每个方面非常重要。如果您习惯了特定的日期/月份/年份格式并且对日期和月份感到困惑，则尤其如此。通过本教程，您应该能够添加您喜欢的任何自定义格式。
How to Change the Date and Time Format on Windows
By default, Microsoft Windows 10 and 11 use dd/mm/yyyy for dates and a 12-hour format for time. This is fіne for moѕt people, but you can сhange the format.
This article will show you how to change the time and date format in Windows 10 and 11 and what each setting does.
How to Change the Date and Time Format in Windows 11
There are two ways to access the date and time format settings in Windows 11. If your clock is displaying incorrectly, or you just want to personalize the format, here’s how to do so:
- Right-click the time and date in the bottom-right corner of the taskbar and select Adjust date and time. Alternatively, you can go to Settings > Time & Language > Date & Time.
- Scroll down and select Language and region.
- Select Regional format under the Region sub-header.
- In the drop-down menu, select Change formats.
- Here, you’ll see several settings for controlling the date and time formats.
We’ll look at these date and time settings in the next section.
Date and Time Format Settings in Windows 11
There are six settings you can change in Windows 11:
- Calendar: Windows uses Gregorian as the default calendar, which many countries worldwide now use (and this is the only option provided). Windows 11 allows you to display two additional calendars—Simplified Chinese and Traditional Chinese—by selecting Don’t show additional calendars in the taskbar under Date & time > Additional settings.
- First day of week: Set any day of the week to be the first day in your calendar. Typically, people prefer either Monday or Sunday.
- Short date: The short date format refers to the all-numerical dd/mm/yy version of the date (for example, 06/18/2022). The short date setting offers several number formats depending on whether you prefer the day, month, or year to appear first. You can also change whether you want to display the date with slashes or dashes.
- Long date: This refers to the written version of the date. This setting allows you to choose whether to display the day (for example, Wednesday) as well.
- Short time: This setting displays the time as a short series of numbers representing hours and minutes (for example, 11:24 AM). There are three variations for the short time format. To change to a 24-hour format, select Short time and select the number without AM or PM displayed.
- Long time: This displays seconds in addition to hours and minutes (e.g., 11:24:36 AM). This setting offers the same variations as short time.
You can also add additional clocks to your taskbar. This is useful when communicating with colleagues or family in different time zones. To do this, open Settings > Time & language > Date & time > Additional clocks.
How to Change Date and Time Format in Windows 10
In Windows 10, the process is more or less the same:
- Press the Windows + I to open the Settings app.
- Select Time & Language.
- In the left-hand menu, select the Date & time formats tab.
- In the top-right sidebar, select Date, time & regional formatting.
- At the bottom of the region settings, select Change data formats.
- Here, you can access the same settings described above.
Note: Like in Windows 11, you can right-click the date and time tab and select Adjust date/time to change the time and date format. You can also access these settings via the Control Panel. To do so, open Control Panel > Clock and Region > Date and Time.
Personalization is Key
You always have to look at your desktop, so formatting each aspect exactly how you’d like it is important. This is especially true if you’re used to a particular date/month/year format and are confused between the day and month. With this tutorial, you should be able to add whatever custom format you like.
