In Germany, millions of families are preparing to enjoy Christmas Eve together, albeit on a reduced scale because of Covid-19 restrictions.
Chancellor Angela Merkel has agreed with state leaders to slightly relax restrictions on private gatherings for the duration of the holiday, with a household allowed to meet with up to four family members from outside their home over the Christmas period.
But despite having scaled back festivities, the coronavirus cases continue to stretch the country's health system. There have been 32,195 new infections recorded in the past day, the second highest since the start of the pandemic and 802 deaths, the fourth highest daily total so far.

After registering two sets of record number of people testing positive for the virus in recent days, there is concern the numbers could rise again with two new variants of the virus found in England.
Medical experts are concerned about the second new variant of COVID-19, labelled 501.V2 which is believed to have originated in South Africa.
Visitors travelling to the UK who have been in or transited through South Africa in the last 10 days will not be allowed into the country after 09:00GMT on December 24.
All those required to quarantine will need to do so for 10 days, along with members of their household. British and Irish nationals are exempt from quarantine restrictions but they will have to self isolate. The UK's Department for Transport says this reflects the "increased risk" during this stage of the pandemic.
The first new variant of the virus was identified in Kent, where currently thousands of trucks and drivers are blocked from travelling across the Channel to mainland Europe.
It was spotted through UK's surveillance system, as the Covid-19 Genomics Consortium (Cog-UK) has tracked the genetic history of more than 150,000 samples of the Sars-Cov-2 virus, which amounts to roughly half the world's genetic sequencing of coronavirus.
