# How to create a DateTime equal to 15 minutes ago?

Each Answer to this Q is separated by one/two green lines.

I need to create a DateTime object that represents the current time minus 15 minutes.

import datetime and then the magic timedelta stuff:

``````In : datetime.datetime.now()
Out: datetime.datetime(2010, 12, 27, 14, 39, 19, 700401)

In : datetime.datetime.now() - datetime.timedelta(minutes=15)
Out: datetime.datetime(2010, 12, 27, 14, 24, 21, 684435)
``````

`````` datetime.datetime.now() - datetime.timedelta(minutes=15)
``````

This is simply what to do:

``````datetime.datetime.now() - datetime.timedelta(minutes = 15)
``````

`timedelta`s are specifically designed to allow you to subtract or add deltas (differences) to `datetime`s.

``````import datetime
datetime.datetime.now() - datetime.timedelta(0, 900)

Actually 900 is in seconds. Which is equal to 15 minutes. `15*60 = 900`
``````

I have provide two methods for doing so for minutes as well as for years and hours if you want to see more examples:

``````import datetime
print(datetime.datetime.now())
print(datetime.datetime.now() - datetime.timedelta(minutes = 15))
print(datetime.datetime.now() + datetime.timedelta(minutes = -15))
print(datetime.timedelta(hours = 5))
print(datetime.datetime.now() + datetime.timedelta(days = 3))
print(datetime.datetime.now() + datetime.timedelta(days = -9))
print(datetime.datetime.now() - datetime.timedelta(days = 9))
``````

I get the following results:

``````2016-06-03 16:04:03.706615
2016-06-03 15:49:03.706622
2016-06-03 15:49:03.706642
5:00:00
2016-06-06 16:04:03.706665
2016-05-25 16:04:03.706676
2016-05-25 16:04:03.706687
2016-06-03
16:04:03.706716
``````

only the below code in Python 3.7 worked for me

``````from datetime import datetime,timedelta
print(datetime.now()-timedelta(seconds=900))
``````

Use DateTime in addition to a `timedelta` object
http://docs.python.org/library/datetime.html

`datetime.datetime.now()-datetime.timedelta(minutes=15)`

`datetime.datetime.now() - datetime.timedelta(0, 15 * 60)`

`timedelta` is a “change in time”. It takes days as the first parameter and seconds in the second parameter. `15 * 60` seconds is 15 minutes.

If you are using `time.time()` and wants timestamp as output

Simply use

``````CONSTANT_SECONDS = 900 # time  in seconds (900 seconds = 15 min)

current_time = int(time.time())
time_before_15_min = current_time - CONSTANT_SECONDS
``````

You can change 900 seconds as per your required time. The answers/resolutions are collected from stackoverflow, are licensed under cc by-sa 2.5 , cc by-sa 3.0 and cc by-sa 4.0 .
