Adjust Day and Month

The Adjust Month setting is only enabled for when a non-ICOUK Adjust Day option (i.e. ICOUK +/- 1) is chosen, e.g. when using the Widgets from outside the UK. It will let you change the Hijri month length from 29 to 30 days and vice versa (if applicable) from the default ICOUK setting.

See example calendar below for adjusting the ICOUK Hijri Calendar to the Saudi Ummul Qura calendar setting for Rajab (Month 7) to Dhul Hijjah (Month 12).
