People are being encouraged to take part in a different type of Darkness Into Light event on Saturday.
It is the largest fundraiser for suicide charity Pieta House, supported by Electric Ireland.
It was scheduled to take place across five continents, and over 250,000 people would have walked against suicide and self-harm.
It has been postponed because of COVID-19, resulting in a funding crisis for Pieta.
Instead, people are being urged to come together - while apart - and take part in the Sunrise Appeal.
This involves getting up at dawn to enjoy the sunrise, mark the moment and join the fight against suicide and self-harm by donating.
Pieta is also asking people to spread the message and offer hope by sharing their sunrise moment using the #DIL2020.
Elaine Austin, CEO of Pieta said: "We’re reminding everyone to set their alarms tomorrow morning for 5am, a lie-in for those of us that regularly do Darkness Into Light.
"This time instead of coming together in our communities physically we will come together around the world symbolically as we all get up and head into our front rooms, gardens or balconies to sit and have a moment while watching the sun rise."
"For those affected by suicide and self-harm the isolation that some of us are currently experiencing will be a familiar feeling.
"That’s the reason we come together on Darkness Into Light - because we don’t want anyone to be alone during times of darkness and isolation.
"Your donation means our counselors can continue to be there for people at their worst moments.
"Your participation shows solidarity and communion with those affected by suicide and self-harm."
Darkness Into Light raised almost €6m last year. People can donate funds online here
