Web alarm clock for 3:43 p.m.
As you hand the chapel decorating over to another volunteer, set the alarm for 3:43 pm so the changeover does not swallow a small but necessary task. You can point out which flowers still need arranging, where the banderitas should hang, or what must be cleared before the patronal fiesta preparations continue towards 4:00 pm.
Because the chapel work is passing into someone else's hands, keep this alarm page open while you finish the handover. Closing the page or the browser stops the alarm, and a sleeping phone may stay silent, so the chapel decorating team could miss the agreed changeover cue. Leave the phone awake, keep its sound audible, and place it where the volunteer taking over can hear it amid conversation and movement.
Before you step away from the chapel in the late afternoon, tell the people at home that 3:43 pm is your cue to wrap up the handover. If they expect you back for merienda, school pickup, or household chores, that shared reference prevents crossed messages. Give yourself a brief buffer for packing ribbons, returning scissors, and saying who holds the keys, rather than treating the alarm as the exact second you must leave.
