It's been a pet peeve of mine for quite some time: formatting dates. Sometimes I really hate other people for the way they format dates. If you're a programmer or computer poweruser you will get what I mean even more.
There are probably thousands of ways to format dates, but there is only one correct way. Of course I'm talking about glorious ISO8601!
ISO8601 provides a beautiful way to format dates. It's simple, clear and easy to understand.
2019-08-09 is the date on which I'm writing this post. It's august 9th, 2019.
The format is very simple and if you can read you can understand it. Year, Month, Day.
YYYY-MM-DD is logical. When you think about it, a year is bigger than a month. A month is bigger than a day.
No more nonsense, I'm looking at you USA! No more 08-09-2019, is that september 8th or august 9th? Also, forget about using a slash, the hyphen is the way to go!
For some reason you have to pay to download (ie read) an ISO standard. Luckily there is a very informative Wikipedia article on ISO8601.
I have listed some key take aways below.
For writing a date:
- Use 4 digits for the year, 2 for month and day. Add zero-padding if needed
For example: 2019-08-09
For writing a date and time:
- Use 4 digits for the year, 2 for month, day, hour, minutes and seconds. Add zero-padding if needed
- Use 24 hour time format
- Seconds can be omitted if desired
- Specify the timezone
For example: 2019-08-09T14:23+02:00
