How to return all events on a specific date in Google Calendar API

Question

i am using Python and Google Calendar API to build a calendar. I would like to get all the events that exist on a given date. The date will be given as a string 'yyyy-mm-dd'. I have created a function that does that but it is still returning the all-day events on the following day.

from datetime import *
import pytz

def get_events_by_date(api_service, event_date):

    split_date = event_date.split('-')

    event_date = datetime(int(split_date[0]), int(split_date[1]), int(split_date[2]), 00, 00, 00, 0)
    event_date = pytz.UTC.localize(event_date).isoformat()

    end = datetime(int(split_date[0]), int(split_date[1]), int(split_date[2]), 23, 59, 59, 999999)
    end = pytz.UTC.localize(end).isoformat()

    events_result = api_service.events().list(calendarId='primary', timeMin=event_date,timeMax=end).execute()
    return events_result.get('items', [])


>>all_events = get_events_by_date(api, '2022-09-24')
>>for event in all_events:
        print(event['summary'])

using this example, it prints all events on the '2022-09-24' AND any all-day events on the '2022-09-25'. Any ideas why? (Or a better way to implement this feature)?

NOTE: i got the idea for the time zone conversion from this post Generate RFC 3339 timestamp in Python

Although I'm not sure whether this is the direct solution to your issue, from your showing script, how about adding timeZone to the request as follows?

From:

events_result = api_service.events().list(calendarId='primary', timeMin=event_date,timeMax=end).execute()

To:

events_result = api_service.events().list(calendarId='primary', timeMin=event_date,timeMax=end, timeZone="UTC").execute()

Reference:

• Events: list
