Sikhs across the United States are holding toned-down Vaisakhi celebrations this week, joining people of other faiths in observing major holidays cautiously this spring as COVID-19 keeps an uneven hold on the country. Vaisakhi, which falls April 13 or 14 depending on which of two dueling calendars one follows, marks the day in 1699 when Sikhism took its current form. While the ongoing pandemic has many people celebrating remotely this year just as in 2020, some, especially in the United States, are joining in masked, socially distant Vaisakhi gatherings.
