With this browser-based application, you can change the format of any calendar date. You can swap the order of year-month-day components, print the full or short name of the month, and print the day of the week of the given date. You can also add or remove date padding and if the calendar date also has a time component, then change it to/from 12-hour and 24-hour formats. Created by computer nerds from team Browserling.

This is a quick online utility for formatting one or more calendar dates. For example, if you have a date "2025-01-24 09:00:00", then you can easily change its format to the month/day/year order, i.e. "01-24-2025 09:00:00", spell out the month as a word, i.e. "January 24, 2025 09:00:00", and add the weekday to the date, i.e "Friday, January 24, 2025 09:00:00". To convert multiple dates at once, specify the dates one per line in the input field. At the moment, the input dates have to have the "YYYY-MM-DD hh:mm:ss" format but coming soon, you'll also be able to customize the input date format. You can format the dates by choosing a format from a list of the most commonly used formats in the options, or create your own date format. To create your own date format, switch to the "custom format" mode and enter a date pattern using the abbreviation for individual date components. For example, the custom format "DD_MMM_YYYY_ddd" will turn a date into "24_Jan_2025_Fri". The valid abbreviations are "YYYY" for a full 4-digit year (such as "2022"), "YY" for a shorter 2-digit year (such as "22"), "MMMM" for the full month name (such as "December"), "MMM" for a 3-character month name (such as "Dec"), "MM" for a 2-digit month value (such as "12"), "dddd" for a full weekday name (such as "Monday"), "ddd" for a 3-character weekday name (such as "Mon"), "DD" for the calendar day (such as "5"), "hh" for a clock hour (such as "12"), "mm" for a clock minute (such as "40"), and "ss" for a clock second (such as "59"). Additionally, you can enable or disable the padding option, which uses the zero-padding method that always makes calendar years 4 digits wide (for example, the year "435" is printed as "0435"), and makes the other components 2 digits wide (for example, the calendar day "5" is printed as "05"). Finally, if you have a full-format calendar date that also has the clock time part, you can switch between the 12-hour and 24-hour clock formats by enabling or disabling the "Switch to 12hr Clock" option. Timeabulous!

In this example, we convert a bunch of unformatted calendar dates to the date format used in the United States/North America. The American date style has a unique order of date components that are month/day/year with a slash character between them. We also apply zero-padding so that all dates have the same width.
In this example, we load three unpadded short dates to the input and convert them into the expanded date notation. The expanded date notation includes spelled month names, spelled days of the week, and padded time and day components.
This example converts dates with a 24-hour clock time component to dates with a 12-hour clock time component. The output date has the format "YYYY, DD MMM hh:mm:ss", which also displays the short name of the month (the "MMM" component). Additionally, each output date has the before-noon/after-noon (am/pm) indicators added to them.
In this example, we create an original date format. We select the custom date format mode and enter the pattern "MMMM(MM) ~ DD ~ YYYY" in the options. The notation "MMMM" means the full month name, followed by "MM" in parentheses, which means the ordinal month number, followed by "DD", which means the ordinal day number, and finally "YYYY", which is the year.
In this example, we change the format of a regular calendar date in the future (from 2050) to an unusual new format. We display the day, month, and year as ordinal numbers, and also add the full name of the day of the week at the end.
