This template inserts the code ‍–‍, producing a U+2013 en dash within two U+200D zero-width joiners, one each on both of its sides. This prevents line break at the endash.

This can be used, for example, to prevent line break as in:

2020–2022 2020–
2022

Using {{nbnd}} (or its aliases: {{nbndash}},{{Non breaking en dash}}) between the years force to produce:

2020{{nbnd}}2022 → 2020‍–‍2022
1952{{nbndash}}1960 → 1952‍–‍1960
1860{{Non breaking en dash}}1865 → 1860‍–‍1865
