# difference in weeks

This block is part of the [`date`](https://docs.rual.nl/block-types/date) group and was last modified in core [`v13.0.7`](https://docs.rual.nl/core-versions/130007).

Difference between 2 given dates in weeks.

- base date `date` Default `now`

- compare to required `date` Will be compared to the base date. If this pin is later than the base date a positive number will be returned.

- rounded diff `number`

- exact diff `number` Will return the exact difference with an accuracy of 3 digits after the comma.

A typical wiring for [difference in weeks](https://docs.rual.nl/block-types/date/date_differenceweeks): [date now](https://docs.rual.nl/block-types/date/date_currentdate) feeds the `date_1` pin; the `number` out pin feeds [cast to value](https://docs.rual.nl/block-types/type%20casting/number_convert_to_value).
