How much does zuzu.codes cost?

The starter track is free — read all lessons and practice for free. Full access to every track (current and future) is $14.99/month. Cancel anytime.

How long does each track take?

Each track is designed as a 30-day challenge — one lesson per day, about 15 minutes each. Go at your own pace, but the structure is built around daily consistency.

What's the lesson format?

Each lesson is a student-teacher dialogue with code examples, followed by a hands-on code challenge in an in-browser editor. You read, you understand, then you write real code.

Do I need prior coding experience?

Our beginner track starts from absolute zero — no prior experience needed. Advanced tracks build on earlier ones, and the platform tells you exactly where to start.

How is zuzu.codes different from freeCodeCamp or Codecademy?

zuzu.codes uses a structured 30-day track format with dialogue-based teaching, an in-browser code editor, and gamification (XP, streaks, progress tracking). The format builds genuine understanding through daily practice.

Find Upcoming Submission Deadlines in Google Calendar — Automation For Researchers

Day 11 · ~12 min●

You have submission deadlines blocked in your calendar. Before the weekly lab meeting, you want to know which ones fall in the next two weeks. Currently, how do you check?

list_calendars from Day 10 gave me the calendar IDs. To find upcoming events I'd open Google Calendar and scan the next two weeks manually. Which I do every Monday.

GOOGLECALENDAR_FIND_EVENT takes a calendar ID and a time_min — an ISO 8601 datetime string. It returns all events starting after that time. Your "next two weeks" query is one function call:

python

result = toolset.execute_action(
    Action.GOOGLECALENDAR_FIND_EVENT,
    {"calendar_id": cal_id, "time_min": time_min}
)
events = result.get("items", [])

What's the time_min format? Is it a timestamp, a date, or a datetime string?

ISO 8601 format: "2026-04-20T09:00:00Z" — date, then T, then time, then Z for UTC. Python's datetime module can generate it: datetime.utcnow().isoformat() + "Z". For a two-week window, add 14 days: (datetime.utcnow() + timedelta(days=14)).isoformat() + "Z". The action uses it as the lower bound — events starting after this time are returned.

So find_events(cal_id, "2026-04-20T00:00:00Z") returns all my deadlines from April 20 onwards? That's the Monday morning calendar check, automated.

The Monday morning calendar check, in one function call:

python

def find_events(cal_id: str, time_min: str) -> list:
    result = toolset.execute_action(
        Action.GOOGLECALENDAR_FIND_EVENT,
        {"calendar_id": cal_id, "time_min": time_min}
    )
    events = result.get("items", [])
    print(f"Found {len(events)} events after {time_min}")
    return events

Three submission deadlines — conference, journal, workshop — all surfaced in milliseconds. That replaces my Monday morning calendar scan.

One consideration: time_min filters events starting after the given time, not events that are ongoing at that time. A multi-day conference block that started before time_min won't appear. For deadline tracking this is usually fine — deadlines are point-in-time events. For finding ongoing availability windows, you'd also need a time_max parameter.

Finding Events with time_min

python

result = toolset.execute_action(
    Action.GOOGLECALENDAR_FIND_EVENT,
    {"calendar_id": cal_id, "time_min": "2026-04-20T00:00:00Z"}
)
events = result.get("items", [])

ISO 8601 format

YYYY-MM-DDTHH:MM:SSZ — date + T + time + Z (UTC). Generate with Python:

python

from datetime import datetime, timedelta
now = datetime.utcnow().isoformat() + "Z"
two_weeks = (datetime.utcnow() + timedelta(days=14)).isoformat() + "Z"

Event dict fields

Field	Meaning
`id`	Event ID for updating or deleting
`summary`	Event title
`start.dateTime`	Start time (ISO 8601)
