Most of the time I just unwrap/except, since this is equivalent behaviour to before.
Alternatives would be changing some APIs to return Results/Options or using alternative functions where possible.
Most occurrences of these calls are in tests anyway where that should not matter.
Some time ago chrono deprecated some functions like NaiveDate::from_ymd and NaiveDate::from_num_days_from_ce. These functions panic if their arguments are out of range.
I replaced the calls to these functions with their recommended alternatives (NaiveDate::from_ymd_opt and NaiveDate::from_num_days_from_ce_opt).
