date_range
Show a date range.
Filter to simplify displaying datetime ranges. When displaying a datetime range, the display of the dates and times often depends if the date parts of the datetimes are equal or not.
Take the following code:
{{ [fromdate, todate]|date_range:[format_ne, sep, format_eq] }}
If the dates of fromdate and todate are equal then the output will
be as if the following were written:
{{ fromdate|date:format_ne }}{{ sep }}{{ todate|date:format_eq }}
However, if the dates are not equal then the output will be as if the following were written:
{{ fromdate|date:format_ne }}{{ sep }}{{ todate|date:format_ne }}
Timezones
Dates in Zotonic are stored in UTC. If a date is displayed then it is converted to the timezone of the current request context. This timezone can be one of the following, in order of preference:
- Preferred timezone set by the user
- Timezone of the user-agent
- Default timezone of the site
- Default timezone of the Zotonic server
- UTC
A specific timezone can be enforced by adding a third parameter to the date_range-filter. For example, to display a date range in UTC:
{{ [fromdate, todate]|date_range:[format_ne, sep, format_eq]:"UTC" }}
Instead of the timezone, the following arguments are also accepted:
