20 Best Free Online Date to Unix Timestamp Converter Websites

Here is a list of the best free online date to Unix timestamp converter websites. Every file on a system has a timestamp of the date and time. This timestamp shows when the file is created or last modified. Unix has its own system of timestamping files. It is called the Unix timestamp. Unix timestamp represents the date and time is different from what you get on Windows or macOS. Instead of showing the date and time in simple human-readable form, Unix timestamp uses a single large number.

Unix timestamp tracks the time as a running total of seconds. This count starts at the Unix Epoch on January 1st, 1970 at UTC. Thus, any Unix timestamp is a number of seconds from that particular date and time. The time you see on a file in Unix is the number of seconds from the Unix Epoch and the time when the file is created/modified. It is very hard to get the actual date and time from that timestamp. Even if you convert the number of seconds to minutes, days, weeks, or years, There are more calculations needed to get the actual year, month, date, and time. But with help of a Unix Epoch converter, you can do it very easily.

This post cover 20 free websites where you can convert a regular date to a Unix timestamp and vice versa. You can simply enter or select the time and date in ISO 8601 format and convert that to a Unix timestamp. I briefly covered each website along with its highlights. You can go through the post to check them out in detail.
