DateToday

This module provides an additional formatter for date fields. This formatter is capable of providing Date strings like "yesterday - 18:00" or "tomorrow - Friday, 9:00".

Configuration

after activating the module, you can configure it on:
* admin/settings/date-time/formats/datetoday

There you can define what level shall has its own presentation, like 'last day' for 'yesterday'. All dates that do not fit selected presentation will use the 'fallback' settings of the field.
