Revert Excel Serial Dates Back to Intended Day.Month Numerics

v0.1.0 · Oct 8, 2025 · MIT + file LICENSE

Description

Detects values imported from spreadsheets that were auto-converted to Excel date serials and reconstructs the originally intended day.month decimals (for example, '30.3' that Excel displayed as '30/03/2025'). The functions work in a vectorized manner, preserve non-serial values, and support both the 1900 and 1904 date systems.
