python - Making a bot that sends messages at a scheduled date with Discord.py

Question

I'm trying to make a bot that sends a scheduled message to a specific text channel. for example at the date of my birthday saying "happy birthday", or also every morning saying "Good morning". The bot seems to don't work since nothing appears in my text channel.

import discord,random,asyncio,os
from datetime import datetime
from discord.ext import commands

token = '#mytokenhere'
bot=commands.Bot(command_prefix='!')

send_time='01:41' #time is in 24hr format
message_channel_id='0000000000000' #channel ID to send images to

@bot.event
async def on_ready():
    print(bot.user.name)
    print(bot.user.id)

async def time_check():
    await bot.wait_until_ready()
    message_channel=bot.get_channel(message_channel_id)
    while not bot.is_closed:
        now=datetime.strftime(datetime.now(),'%H:%M')
        if now.hour() == 1 and now.minute() == 52:
            message= 'a'
            await message_channel.send(message)
            time=90
        else:
            time=1
        await asyncio.sleep(time)

bot.loop.create_task(time_check())


bot.run('token')

Here's how you would do something like this using the tasks extension

from discord.ext import commands, tasks

bot = commands.Bot("!")

target_channel_id = 1234

@tasks.loop(hours=24)
async def called_once_a_day():
    message_channel = bot.get_channel(target_channel_id)
    print(f"Got channel {message_channel}")
    await message_channel.send("Your message")

@called_once_a_day.before_loop
async def before():
    await bot.wait_until_ready()
    print("Finished waiting")

called_once_a_day.start()
bot.run("token")
