# Symmetric time generator

World's simplest time tool
With this browser-based application, you can generate palindromic clock times with symmetrical time components (such as 03:30 or 12:33:21). In the options, you can specify any time period and in the output, you'll get padded or unpadded clock palindromes that use either 12-hour or 24-hour clock format. Created by computer nerds from team Browserling.

## What is a symmetric time generator?

learn more about this tool
This is a quick online utility for generating palindromic clock times and timer values. A palindromic time (also known as a symmetrical time) is one where the minutes are a mirror reflection of the hours in the "hh:mm" format. For example, palindromic clocks in the "hh:mm" format are "12:21" and "02:20". As you can see, if this time is read from left or right, it says the same time. If a clock is in the "hh:mm:ss" format, then the seconds are a mirror reflection of the hours and the minutes always consist of two equal digits (or a single unpadded digit). For example, palindromic clocks in the "hh:mm:ss" format they are: "10:22:01", "5:33:5", "22:4:22", and "1:9:1". Our program finds all such clock times throughout the day or a restricted time interval and outputs a list of them in random order. In the options, you can specify the number of symmetric times you need, as well as fine-tune the search range. For example, the start of the range could be "10:00:00" and the end of the range "10:30:00". In this case, the program will display three padded timers "10:11:01", "10:00:01", and "10:22:01". If the start of the range is not set, it's assumed to be "00:00:00". If the end of the range is not set, it's assumed to be "24:00:00". Symmetrical timers can be padded, like "10:22:01", unpadded, like "5:33:5", or mixed padding, like "01:4:10" (hours here are padded but minutes aren't padded). You can switch between the three padding modes in the option and get different sets of palindromic times for each mode. You can also select the clock format that uses all three time components "hh:mm:ss" or the shortened format "hh:mm". Additionally, you can switch between 12-hour and 24-hour time formats. Timeabulous!

## Symmetric time generator examples

Click to useDigital Watch Palindromes

In this example, we generate six palindromes on a 24-hour digital watch that also includes the seconds value. A digital watch uses full two-digit time components that are picked from the entire day (we left the start-time and end-time options blank, so the time range is set to be from 00:00:00 to 24:00:00).

Find symmetric time in
24-hour clock format.

Palindromic HH:MM Time

In this example, we switch to the shortened time format consisting of only hours and minutes "hh:mm" (no seconds). In such clock times, the hours are a mirror image of the minutes, with respect to the colon symbol. In the output, we calculate nine padded times and print them to the screen in a vertical column.

Find symmetric time in
12-hour clock format.

Unpadded Symmetric Timers

In this example, we create a dozen palindromic timers in the first part of the day. We set the beginning timer to "00:00:00", the end timer to "12:00:00", and generate non-padded symmetric timers (which means hours, minutes, and seconds values will have a single digit if they are less than 10).

12-hour Palindromic Times

This example generates symmetrical time in a 12-hour clock format. It starts the generation at noon, ends it at midnight, and displays eight "pm" times.

12:44:00 pm
04:55:40 pm

Find symmetric time in
12-hour clock format.

Symmetric Night Time

In this example, we generate symmetric time from a nighttime range that starts at 9 pm (21:00) and ends at 3 am (3:00). We turn on the mode for generating mixed time, which allows the program to create time values with full padding (such as 02:22:20), with no padding (such as 01:3:10), and with partial padding (such as 00:5:00).
