Release 3 of the Create Time Dimension App is now live. This version brings Czech language support and ISO-8601 week numbers.
The update is made on the server so it is available for everyone right away, no update needed on the Excel/Client side.
Big thanks to Petr Havlik (Twitter: https://twitter.com/petrhavlik) for helping with the Czech translation.
Please note that the ISO-8601 week numbers are just one way of expressing week numbers and might not be what you want. The week numbers start on Mondays per definition and does not change when changing the week start day. If you would like to use another week numbering format you can still add a column using the =WEEKNUM(date, week number system) formula in Excel.
