Simple quarter support for python datetime.date

Setup

1. Install via pip (pip install datetime-quarter)
2. or via git (git clone "https://github.com/BetaS/datetime-quarter")
3. Check availability in your project like below

from datequarter import DateQuarter

sample = DateQuarter(2019, 4)
print(sample)  # 2019 4Q

Operations

1. Creation

• item = DateQuarter(2019, 4) # 2019 4Q
• item = DateQuarter(2018, 8) # 2019 4Q for convinience
• item = DateQuarter.from_date(datetime.date(2019, 12, 31)) # 2019 4Q

2. Adding or sub quarter

• DateQuarter(2019, 4)+1 # 2020 1Q
• DateQuarter(2019, 4)-4 # 2018 4Q

3. Getting distance

• DateQuarter(2019, 4) - DateQuarter(2019, 1) # 3Q
• DateQuarter(2019, 1) - DateQuarter(2019, 4) # -3Q

4. Comparison of DateQuarter

• DateQuarter(2019, 1) > DateQuarter(2019, 4) # False
• DateQuarter(2019, 1) < DateQuarter(2019, 4) # True
• DateQuarter(2019, 1) == DateQuarter(2019, 4) # False
• DateQuarter(2019, 1) != DateQuarter(2019, 4) # True
• also support >= and <=

5. Comparison of datetime.date

• datetime.date(2019, 12, 31) in DateQuarter(2019, 1) # False
• datetime.date(2019, 12, 31) in DateQuarter(2019, 4) # True
• also support >, >= and vice versa

6. Getting start and end date

• DateQuarter(2019, 1).start_date() # datetime.date(2019, 1, 1)
• DateQuarter(2019, 1).end_date() # datetime.date(2019, 3, 31)

7. Iterate over containing date

quarter = DateQuarter(2019, 1)
for day in quarter.days():
    print(day)  # [datetime.date(2019, 1, 1), ..., datetime.date(2019, 3, 31)]

8. Iterate between DateQuarter

start = DateQuarter(2019, 1)
end = DateQuarter(2019, 4)
for quarter in DateQuarter.between(start, end):
    print(quarter)  # [DateQuarter(2019, 1), DateQuarter(2019, 2) , DateQuarter(2019,3)]

• also it support reversed case
