Odoo provides some functions to create date and time objects. These are specific to certain periods like “month”, “quarter”, “fiscal year”, etc. Also in the date_utils, there are a couple of abstractions to make simple date calculations.

• The fields.Date. today() function returns a string with the current date in the format YYYY-MM-DD.

Eg :

 print('Today = ', fields.Date.today()

Output :   

Today =               2023-04-09

• The Odoo field.DateTime. now() function returns the current date and time in the format YYYY-MM-DD HH:MM: SS.

Eg:

print('Today = ', fields.Datetime.now())

Output :

Today =  2023-04-09 08:12:59

• We can import the package date_utils into the module by using

from.odoo.tools import date_utiles

Let’s Discuss some default functions of date utils.

(1) start_of()

Get the start of a time period from a date or a datetime. Start of hour, day, week, month, quarter, and year. start_of(value, granularity) value is the initial date or datetime. Granularity is the type of periods like year, quarter, month, week, day, or hour.

Eg :

print('starting_hour',date_utils.start_of(today, "hour"))
print('Today = ', fields.Datetime.now())
print('starting_day',date_utils.start_of(today, "day"))
print('starting_week',date_utils.start_of(today, "week"))
print('starting_month',date_utils.start_of(today, "month"))
print('starting_quarter',date_utils.start_of(today, "quarter")) print('starting_year',date_utils.start_of(today, "year"))

Output:

Today =  2023-04-09 09:54:05
starting_hour 2023-04-09 09:00:00
starting_day 2023-04-09 00:00:00
starting_week 2023-04-03 00:00:00
starting_month 2023-04-01 00:00:00
starting_quarter 2023-04-01 00:00:00
starting_year 2023-01-01 00:00:00

(2)   end_of()

In Odoo datetime field, Using the end_of function we can get the ending of hour, day, week, month, quarter, and year of date or datetime. end_of(value, granularity) value is the initial date or datetime. And granularity is the Type of periods like year, quarter, month, week, day, or hour.

Eg:

print('Today = ', fields.Datetime.now())	
print('ending of hour =',date_utils.end_of(today, "hour")) print('ending of day =', date_utils.end_of(today, "day"))
print('ending of week =', date_utils.end_of(today, "week"))
print('ending of month =', date_utils.end_of(today, "month"))
print('ending of quarter =', date_utils.end_of(today, "quarter")) print('ending of year =', date_utils.end_of(today, "year"))

Output :

Today =  2023-04-09 09:10:37
ending of hour = 2023-04-09 09:59:59.999999

(3)   add()

Return the sum of value and a relativedelta. We just need to mention the correct number of days.

• date_utils.add(today,days=1) function add one days with today
• date_utils.add(today,weeks=1) function add one weeks with today
• date_utils.add(today,months=1) function add one month with today
• date_utils.add(today,years=1) function add one year with today
• date_utils.add(today, days=2, months=6, years=1) we can also add days, months, and years together.

Eg

print('Today = ', fields.Datetime.now())
print('add days =',date_utils.add(today, days=1)) print('add week =',date_utils.add(today, weeks=1))
print('add month =',date_utils.add(today, months=1)) print('add year =',date_utils.add(today, years=1))
print('add day and year and month =',date_utils.add(today, days=1, months=1, years=1))

Output :

Today =  2023-04-09 09:20:13
add days = 2023-04-10 09:20:13
add week = 2023-04-16 09:20:13
add month = 2023-05-09 09:20:13
add year = 2024-04-09 09:20:13
add day and year and month = 2024-05-10 09:20:13

(4) Subtract ()

Return the difference between value and a relative delta. Passing the parameter number of days to be subtracted from the current date and time.

• date_utils.subtract(today, days=1) function one day subtracted from the current date and time.
• date_utils.subtract(today, weeks=1) function one week subtracted from the current date and time.
• date_utils.subtract(today, months=1) function one month subtracted from the current date and time.
• date_utils.subtract(today, years=1) function one year subtracted from the current date and time.
• date_utils.subtract(today, days=2, months=6, years=1) we can subtract days, months, and years from the current day and time together.

Eg

print('Today = ', fields.Datetime.now())
print('subtract day =',date_utils.subtract(today, days=1))
print('subtract week =',date_utils.subtract(today, weeks=1))
print('subtract month =', date_utils.subtract(today, months=1)) print('subtract year =', date_utils.subtract(today, years=1))
print('subtract day and month =',	date_utils.subtract(today, days=2, months=6))

Output :

Today =  2023-04-09 09:32:04
subtract day = 2023-04-08 09:32:04
subtract week = 2023-04-02 09:32:04
subtract month = 2023-03-09 09:32:04
subtract year = 2022-04-09 09:32:04
subtract day and month = 2022-10-07 09:32:04

(5)   get_month()

get_month = date_utils.get_month(today) It returns the range from the first day of the month to the last.

Eg:

print('Get month =',date_utils.get_month(today))

Output :

Today =  2023-04-09 09:39:25
Get month = (datetime.datetime(2023, 4, 1, 0, 0),
datetime.datetime(2023, 4, 30, 0, 0))

(6)get_quarter()

get_quarter = date_utils.get_quarter(today) It returns the range from the first day of the fiscal quarter to the last.

Eg :

print('Get Quarter =', date_utils.get_quarter(today))

Output :

Today =  2023-04-09 09:48:29
Get Quarter = (datetime.datetime(2023, 4, 1, 0, 0),
datetime.datetime(2023, 6, 30, 0, 0))

(7)get_quarter_number()

quarter_number = date_utils.get_quarter_number(today) It returns the number of the current quarter.

Eg :

print('Get Quarter Number =', date_utils.get_quarter_number(today))

Output :

Today =  2023-04-09 09:51:54
Get Quarter Number = 2

(8) get_fiscal_year()

fiscal_year = date_utils.get_fiscal_year(today) It returns the range from the first day of the fiscal year to the last.

Eg :

print('Get Fiscal Year =', date_utils.get_fiscal_year(today))

Output :

Today =  2023-04-09 09:54:05
Get Fiscal Year = (datetime.datetime(2023, 1, 1, 0, 0),
datetime.datetime(2023, 12, 31, 0, 0))

(9)context_today()

today = fields.Date.context_today() Return the current date as seen in the client’s timezone in a format fit for date fields.

Eg :

print('context', fields.Date.context_today(self))

Output :

context 2023-04-09

(10)   context_timestamp()

It returns the given timestamp converted to the client’s timezone.

Eg :

print('Context timestamp =',
Today =	2023-04-09 10:14:00
Context timestamp = 2023-04-09 15:44:00+05:30

Output :

Today =  2023-04-09 10:14:00
Context timestamp = 2023-04-09 15:44:00+05:30

(11)  to_date()

fields.Date.to_date(value) It converts the value to a date object.

Eg :
