DateComparison

[mb6852]

What is the preferred method to perform comparison on a date column?

[RobinL]

To use date comparisons in Splink, first import the comparison library:

import splink.comparison_library as cl

Two useful comparisons for dates are:

1. cl.DateOfBirthComparison()
2. cl.AbsoluteDateDifferenceAtThresholds()

These can be used in your Splink settings to compare date fields with various levels of precision and tolerance.

Thank you for your reply. AbsoluteDateDifferenceAtThresholds() is not listed here https://moj-analytical-services.github.io/splink/api_docs/comparison_library.html but it is included.

Thanks. It's because they aliases. Fixed here:
