About Calendar Bulk: Bulk Delete & Edit for Google Calendar
Google Calendar only lets you change one event at a time. Calendar Bulk lets you select hundreds and change them together.
Pick a calendar and a date range, narrow it down by title, color or who organized it, tick the events you want, and then:
• Delete them: clear duplicated imports, old classes, or anything else in a range
• Move them to another calendar you can edit
• Reschedule them by minutes, hours, days or weeks (a 9:00 meeting stays at 9:00, even across a clock change)
• Recolor them so a group stands out
Careful by default
• Select duplicates in one click, keeping one of each
• Undo the last change with one click
• Guests aren't emailed unless you choose to tell them
• Shift-click to select a whole range of events
Private by design
Calendar Bulk talks to Google Calendar straight from your browser. Your events are never sent to us or anyone else. Works with any Google account, including work and school accounts that allow third-party apps, in Chrome, Edge and Brave on desktop.
Try it free on your first 30 events. Unlimited is a one-time $9 purchase with a 14-day refund.
