For Candice Ingram, 39, Sundays have become an unofficial dating strategy day. While her coupled-up friends are busy doing couple-y things, the Mosman marketing and events manager is usually re-grouping and going through her eHarmony matches for the week. 

After a busy week of work and socialising with friends, it usually takes her until Sunday to think about her dating situation.

"It's my day of rest and re-grouping," she says. "It's when I'm in the head space to sit down and go through the messages I have and think about who seems nice." 

Ingram is certainly not the only single more likely to be looking for love on a Sunday. Over the past six months, dating website RSVP (owned by Fairfax Media, publisher of The Sun-Herald) has had 20 per cent more sign-ups, 22 per cent more "kisses" sent and 21 per cent more activity on the site on Sundays than on other days of the week. 

Tinder and eHarmony also report increased traffic on Sundays, while Oasis says traffic goes up on a Sunday but, for them, peaks on a Monday.

"Being the end of the week, Sunday is a time when singles look back and review what has been going on in their social life – did they meet anyone interesting? Did their dates work out? Did they make the most of the weekend?" says RSVP spokesperson Kari Taylor.

Taylor says RSVP has been gearing up for a particularly busy day today. "Valentine's Day brings the state of your love life to the fore, so February 15th is always a busy day on our site and this year it falls on a Sunday," she says. 

Melanie Schilling, eHarmony dating and relationships expert, says singles often report feeling lonelier on Sundays. "Sunday is often reserved for couples or family time, so singles are often left to their own devices when their coupled-up mates are unavailable," she says. "Sunday can also be a time of reflection as we consider the previous week and prepare for the coming week – this can promote questions like, 'Where am I going in my life?' and, 'Why am I still single?'"

Sexologist and relationship expert Dr Nikki Goldstein, who is single herself, says that singles often suffer a "dating hangover" on Sundays.

"You might have gone out to a bar on a Saturday night and realised how terrible it is to meet somebody in an alcohol-fuelled environment," she says. 

"We get to the point where we think, 'I just don't want to meet somebody that way anymore', so we go online."
