在开始日期和结束日期内生成所有季度

import datetime

def generate_quarters(start_date, end_date):
    quarters = []
    current_date = start_date

    while current_date <= end_date:
        quarter_start = current_date.strftime("%Y-%m-%d")
        quarter_end = (current_date + datetime.timedelta(days=89)).strftime("%Y-%m-%d")
        quarters.append((quarter_start, quarter_end))
        current_date += datetime.timedelta(days=90)

    return quarters

# 示例用法
start_date = datetime.datetime(2022, 1, 1)
end_date = datetime.datetime(2023, 12, 31)
quarters = generate_quarters(start_date, end_date)

for quarter in quarters:
    print("Quarter Start:", quarter[0])
    print("Quarter End:", quarter[1])
    print()
