How to generate datetime array for years in Python using UliEngineering

You can easily generate a NumPy datetime64 array for a range of years using the UliEngineering Python library:

generate_years.py
import numpy as np
from UliEngineering.Utils.Date import *

# Generate datetime array for 2020-2024
years = generate_years("2020-01-01", "2024-12-31")
print(f"Years 2020-2024: {len(years)}")
print(f"First year: {years[0]}")
print(f"Last year: {years[-1]}")

# Generate datetime array for a decade
years = generate_years("2020-01-01", "2029-12-31")
print(f"\nYears in a decade: {years}")

Example output

generate_years_output.txt
Years 2020-2024: 5
First year: 2020-01-01
Last year: 2024-01-01

Years in a decade: ['2020-01-01' '2021-01-01' '2022-01-01' '2023-01-01' '2024-01-01'
 '2025-01-01' '2026-01-01' '2027-01-01' '2028-01-01' '2029-01-01']

The generate_years() function returns a NumPy datetime64 array containing January 1st of each year from the start year (inclusive) to the end year (inclusive).
